Thousands more homes will be available to council tenants when three local authorities merge their housing stocks online.
Vacant properties in Lincoln, North Kesteven and West Lindsey will be listed on the new Lincs Homefinder website from mid to late-December.
It will include council houses as well as properties belonging to housing associations, such as Acis.
Potential tenants will be able to browse the properties and complete an application form online.
They will then be assessed based on their needs, which will allow them to "bid" for properties.
The site will replace the Lincoln Homefinder website, which only operates across the city.
It will also replace the current system in West Lindsey and North Kesteven, where tenants are offered a house chosen for them by the council.
Housing officers say that the unified scheme will make it easier for applicants, giving them the power to choose the property, area and tenure they wish to live in.
Councillor Stewart Ogden, executive member for housing at NKDC, said: "The scheme has been designed as easy to use, with the highest level of customer service, and enables people to make the best choice for their needs from the full range of housing options available to them.
"It will be a fairer, more efficient and transparent way of letting the current supply of social housing.
"By widening the options for people and giving them a more active choice in where they live, we also hope that tenants will be more active in contributing to their neighbourhood.
"And by opening up the full range of properties available, we also hope to level out areas of high and low demand, prevent homelessness and reduce the use of temporary accommodation."
Lincs Homefinder was initially approved in August 2010 after extensive consultation between those on the housing register, tenants, support agencies and housing associations.
But "technical issues" with the development of an IT system means that there has been significant delays in implementing the new scheme.
Malcolm Parish, chairman of the Prosperous Communities Committee at West Lindsey District Council, said: "This has been a long time in coming forward but we were keen to make sure we developed the scheme as effectively as possible.
"What we have now is the opportunity for people to have a real choice in where they can live.
"This scheme is not only for would-be tenants but it is open to existing tenants who wish to change their current home.
"We are excited to be part of this scheme, which is a fantastic example of local authorities working together to improve services for all our residents."
And the City of Lincoln Council's strategic housing manager, Alison Timmins, added: "It will be a much more user-friendly system with better information for applicants.
"The key is that the partnership should make it easier for people to move within central Lincolnshire when they need to do so for work or personal reasons and will mean greater mobility for people across the three areas."
