State Real Estate Cadastre Information System (Cadastre) Number of objects in Cadastre (on 01.09.2006):

Real property objects: land units ~ 950 000 constructions ~ 1 350 100 groups of premises ~ 1 652 400

Real estate: land estate (land with buildings incl.) ~ 676 000 building estate (land for rent) ~ 37 800 apartment properties ~ 532 500

Development of Mass (Cadastral) Valuation in Latvia (1) After restitution of independence (1990), enforcement

of land reform took place in Latvia: main tasks of land reform – restitution of property

rights (for real owners and their inheritors); restitution of property rights has constitute ground

for development of land valuation principles. Until the year 1994 – cadastral valuation (agricultural

land) and inventory of buildings and structures (replacement of building costs) has based on formerly applied approaches (valuation methods).

From the year 1994 – introduction of new, on the market data based approach for valuation of urban land (land value zonings).

Development of Mass (Cadastral) Valuation in Latvia (2) In 1997 – first mass valuation took place for the purpose

of real property taxation. From the year 1998 Law “On Real Property Tax” became

into force, and mass valuation procedure obtained obligatory status.

In the year 2000 – valuation of buildings took place for cadastral valuation purposes.

Until the year 2006 – updating of cadastral values take place for municipal units (towns and rural municipalities) and groups of objects of valuation (land, buildings).

From the year 2006 Law “On Cadastre” became in to force for regulation of Cadastre system, included cadastral valuation (first law on Cadastre after gaining of independence and starting point for transition period of existed cadastral valuation system).

Legal Framework

Cadastral (mass) valuation:

Law “On Cadastre" – into force since January 1st, 2006;

Regulations of Cabinet of Ministers “Regulations on Cadastral Valuation” – Regulations # 305; April 18th ; 2006.

Procedures

Procedure of cadastral valuation:

State Land Service (SLS) – responsible institution for cadastral valuation of real property (development of value zonings and determination of indexes of cadastral value basis – base values and correction coefficients);

Cabinet of Ministers – conforms value zonings and cadastral valuation indexes;

SLS – automated valuation according data of Cadastre (all registered objects).

Work Organization (SLS)

Organization of procedures take place in three levels:

Central unit – development of methodic and models, analysis of market data (for all country), participation in development of cadastral valuation indexes, management of cadastral valuation process in general;

Regional centers (8) – coordination of cadastral valuation process in local level (bureaus);

Bureaus (28) – development of value zonings (local administrative units) and participation in the development of cadastral valuation indexes.

Software

Collection and processing of market data – special program on the platform of Oracle: for data collection – online processing transactions

data base (OLTP); for data processing – online analytical processing data

base (OLAP), Oracle Discoverer. For statistic processing of data – “Statistical Package

for the Social Sciences” (SPSS). For testing of indexes of cadastral valuation – special

software on the Oracle platform; for data processing – OLAP data base, Oracle Discoverer.

Automated valuation of objects – all models are integrated in Cadastre System (special software, on the Oracle platform).

Development and Testing of Valuation Models Determination of characteristic data of valuation

objects which theoretically have impact on value according comparable (similar) objects in Cadastre System;

Creation of experimental model of valuation;

Determination impact of used factors according methods of statistic analysis;

Testing of cadastral valuation indexes (basic values, correction coefficients etc.);

Regular testing of cadastral valuation indexes (take place after valuation of all objects).

Determination of Indexes for the Purpose of

Cadastral Valuation until the year 2006 Development of cadastral valuation indexes and

value zonings took place for all groups of valuation objects within administrative units (urban and rural).

Problems: cadastral valuation indexes and value zonings are

developed for particular municipalities and whole state is not treated in the same time:

unequal situation between municipalities; discrepancy with real estate market.

cadastral valuation indexes of land and building are developed not in the same time;

special development proposal is needed – prescribed procedure;

municipalities have wide possibilities to affect results – procedure of conforming.

Determination of Indexes for the Purpose of Cadastral Valuation after the year 2006

Regular (each 4th year) determination of cadastral valuation indexes take place for specific valuation objects (type of property) in the same time for land and buildings: For rural properties – development of zonings of agricultural

land and forest land – on the first time in the year 2007; Residential properties – development of residential properties

zonings – on the first time in the year 2007; Industrial type of property – development of industrial properties

zonings (as well as determination of indexes for engineering structures) – on the first time in the year 2008;

Commercial and public property – development of commercial properties zonings – on the first time in the year 2009.

Estimation of real estate market correction coefficients will take place after two year time period for each developed value zoning (other indexes will remain unchanged).

Methods of Valuation

To determinate indexes for cadastral valuation purposes are used internationally well-known methods of valuation: Sales comparison method –

the most applicable method – for valuation of land for construction and agricultural properties; as well as for development of cadastral valuation basis for building cadastral valuation;

Income (capitalization) approach –for development of cadastral valuation basis of forest land;

Coast approach method –for development of cadastral valuation basic values of buildings and engineering structures.

Applicable Information

For development of indexes of cadastral valuation and value zonings: Real estate market data (sales and rent information,

construction costs, supply and demands, market trends and activity);

Undirected information – main factors of impact on sales prices (on the basis of market data analysis);

Local territorial plans and detail plans, other information regarding infrastructure development;

Information of legal acts (borders of preservation areas, nature preservation areas);

For mutual comparison of municipalities – social economic information of the specific municipality, statistics – unemployment, number of economic active population, demographic data etc.

Application of Market Information

Regular updating of data base (actual information): real estate market data from Land Book Register (legal

agreements); characteristic data from Cadastre System.

All developments – based on the real estate market information (for the time period no less than 2 years).

Selection of data for development of cadastral valuation indexes: mathematic approach – for separation of untypical data; individual approach – manual evaluation of data and

comparison of data with accessible information.

Object of Valuation

Land – according use of the land: Land for construction purpose – 9 groups, incl.:

Land for single residential houses; Land for multilevel residential buildings; Land for construction of commercial objects; Land for industrial objects.

Rural (agricultural) land – 3 groups, incl.: Agricultural (arable) land; Forest land; Land under waters.

Buildings – 105 types of buildings (9 groups);

Engineering Structures – 703 types (89 groups);

Real property.

Land for Construction (1)

Main factors of valuation of land for the construction purpose:

Land area (m2); Location (in the country, with in borders of

municipality); Restrictions of land use; Use of real property (land use type).

Land for Construction (2)

Algorithm (formula) for calculation of cadastral value:

Kv – cadastral value (in Latvia's currency, lats; Ls);

Bv – basic value of land for construction use (Ls/m2);

PLM – area of land use type (m2);

Ksamaz – correction coefficient of area;

KT – market correction coefficient;

Kapg – correction coefficient of impact of restrictions;

Kp – correction coefficient of pollution.

Real Property

Cadastral value of real property can be estimated as a sum of cadastral values of related objects (land, located buildings and engineering structures).

Cadastral value of apartment can be estimated as a proportional part from sum of cadastral values of building, land under building and related functional buildings.

Accessibility of Information

Value zonings and indexes of cadastral value basis of all municipal units are accessible in website of SLS www.vzd.gov.lv.

Application of Cadastral Value

For real property taxation (main task); For stamp fees (Land Book fee, inheritance

fee etc.); For land rent (in cases of enforced rent); For privatization of land under constructions; For rent of unprivatized rural state and

municipal land; For estimation of value of comparable land; For enforcement of land reform (estimation of

number of vouchers).

Future Development

Improvement of graphic data of value zoning maps (for the purpose of automatic zoning updating) – In present automated zoning updating take

place once a year (other time manual work); Digitization of fertility maps (agricultural land) –

development of data basis – In present all actions are manual;

Improvement of valuation model of residential houses (additional characteristics – well equipped, etc) – In present there are some empty windows in

Cadastre (no information or registration is not completely done).

Improvement of graphic information of market data (automatic maps of transactions) – In present all market data maps are manual.
