Property assessment companies (PACTs) work with property owners and property managers to decide how much land they should pay to develop and improve.
The companies are also required to provide a detailed assessment report and a list of all relevant land uses, which is then published on their website.
The company also provides financial assistance to property owners for certain types of development.
PACTs are usually located in rural and suburban areas.
The number of PACT companies in Ireland has increased in recent years.
In 2015, there were 4,816 PACT units, of which 1,872 were owned by small properties.
In 2017, there are 5,828 PACT property owners, of whom 2,853 are small properties (including small detached houses, apartments and townhouses).
In 2017-18, there was an average of 1,000 applications a year to PACT properties.
The majority of the properties that were assessed are located in the north of the country.
In the south, PACT has more of a focus on large estates and on properties owned by foreign investors.
There are currently 5,500 property owners in the south of Ireland with an average value of €100 million (around £75 million).
Source: PACT statistics on property owners Source: Property Assessors Association of Ireland (PAAI) article The PAAI statistics on properties owners also reveal that the percentage of owners who are small property owners is relatively high in comparison to the rest of the Irish population.
The average PACT owners share of the population is around 19 per cent (around 2.2 million people).
The PPAI statistics also show that there are more owners who own smaller properties than the rest.
For instance, in 2016, there could be more than 2.5 million people in the country who were small property owner.
For those owners, there is also a high proportion of owners with smaller properties (30 per cent) compared to owners with larger properties (22 per cent).
This is also reflected in the percentage ownership of property owners who have a primary home (40 per cent of the total).
The highest proportion of the owners with a primary house are in the rural areas (39 per cent), while the most remote areas are in Dublin (28 per cent, followed by Galway (25 per cent)).
There are also a number of areas in the northern and eastern counties which have high numbers of owners of small properties, such as Clondalkin (39%), the Fermanagh-Monaghan (30%), Clare (27%), the Derry-South Tyrone (26%) and the Louth (25%).
For those that own smaller houses, the median age of the owner is between 32 and 34 years old.
In comparison to other parts of the world, Ireland has a relatively high number of owners (30,851) who have no children (16,741), while owners with children have a higher proportion of owner ages between 25 and 29 years old (17 per cent and 16 per cent respectively).
The majority (55 per cent; 25,923) of owners are male and the largest percentage of male owners are aged 30 to 34 (23 per cent); in contrast to the general population, the number of female owners is higher (15 per cent compared to 10 per cent for males).
PACT ownership rates for property owners The proportion of PDAI owners who hold a primary or secondary home is similar across the country, with almost half of owners in Fermanah-Monaghlin, Cork and Dublin owning their home on a primary and secondary basis.
PPAIs ownership of primary houses is significantly lower than the majority of owners, however.
The percentage of PPAIS owners owning their primary home on an individual basis is only 12 per cent.
The highest percentage of primary owners are in Clare (42 per cent versus 35 per cent among owners of secondary houses).
Owners with a secondary home are also slightly more likely to own their home in a primary dwelling (25.8 per cent vs 16.6 per cent per home).
The lowest percentage of secondary owners is in the west of the county (16.4 per cent against 14.7 per cent on primary dwellings).
The percentage holding a secondary house is slightly lower in the Dublin area, where the proportion holding a primary residence is around 16 per in the total population (17.4%).
The percentage owning a primary (secondary) dwelling is lower in all of the counties but is significantly higher in Clare and Cork.
This is reflected in a higher percentage of owner aged 30 and over in Clare than in other counties (18.3 per cent in the Clare area versus 11.9 per cent across the rest).
The number and percentage of homeowners who own properties of a lower than average quality also varies significantly across the county.
The median value of the homes assessed by PAAIs is €2.2m (€1.9 million in Dublin). For those
