The name " houses 2 buy " IMO has some limited possibilities in its' marketplace.
Often times I see bright signs on the road shoulder at busy intersections / stop lights stating
" will make offer to buy your home ", or " we buy houses in any condition " , etc.
The signs usually have a big bold lettered URL on 'em and your domain might work for that marketplace.
Some companies may be local while others may be national.
Also see print ads for the same types of houses wanted.
