My son looked at some foreclosure houses before he bought the one he has. There are definitely some differences between them and regular sales. HUD houses are not foreclosures; but I am not sure if a foreclosure can be a HUD also (so I am no use there, sorry). Early on, one of our houses was a HUD style mortgage. Every time my husband got a raise, they took it and added it to the mortgage. So, saving money-wise we never could get ahead. We stayed in that mortgage for almost ten years, not smart. We should have sold or switched over after two years, like our neighbors (who had the same type mortgage) did. I think having a VERY knowledgeable realtor in HUD and forclosure mortgages would be a good idea. Make sure you are very clear on all the aspects of everything involved in whatever you are looking at. HUD's help a lot of people out. Foreclosure's can get you a good deal on a home that should be priced a lot higher. But make sure you have a good inspector go over the homes to make sure there are no hidden defects. I am not a realtor; but my sister worked for an appraiser and a realtor for a number of years and I learned some things from her; plus our own experiences over our years. Just do your research.
