i don't know where to go to see the houses and guild halls would like to know how and where to look these up thank you

Talk to Mathew, at mountain, west from depot. But, you will need premium to bid from house. If you want house from Bersund, talk to Lasse at castle. You just have to say "hi" and "bid" to see the list of available houses, and their prices. But, about look and location, you just have to search from map.
