Perfect Homes can help you ...
Google them....They speak English & their website allows search by cost & area....
The best way is to explore MuBaans with your wife & look at homes with signs then negotiate from there.....
BEWARE of farang real estate "brokers"....They will gladly rent you something for 25-30,000 a month that you can find for 9-14,000 by doing your own investigating.....
Just cruise the areas you like & call numbers found on signs.... Usually, the locals have their own (very) helpful network....
Set your budget & stick to it and you'll find what you want within a month or two.....
Perfect Homes will have an agent that speaks English drive you around....They don't squeeze you to make the sale.....And, they will stay at the high end of listings unless you either select from their website & have them show the listings you have picked out - or you just grind it out through all the showings until you find one.....
The locals pipeline / networking always worked best for us....You get that insider, neighborly input about area, traffic, markets, noise, people that casual outsiders don't have a grasp on.....
