What lenders look at in Mount Gambier
Mount Gambier is a regional city of houses. Here's what tends to come up with lenders.
Regional valuations
Valuers rely on recent local sales and regional cities have fewer of them than capitals. A valuation below the contract price means a bigger deposit, so build in some room.
Unit size
One LMI provider's public guidelines need units to have at least 30 m2 of living area, excluding balconies and car space. Check the floor plan of smaller units early.
Company title
Mount Gambier is far more than 10 km from a capital city CBD. One LMI provider's public guidelines treat company title as unacceptable there, so check the title type of any older block of units.
Larger blocks on the edge
Homes on bigger blocks on the city's edge can be valued differently from suburban houses. One LMI provider's public guidelines accept rural residential properties up to 50 hectares that aren't income producing. Sheds and stables are noted but left out of the value.
