I am from NJ so wanted to know if any local Pittsburgh investors know of any GC that would be able to run a project from the foundation up.

If you run into any issues needing a repair man or contractor, I have a great person I can give you his contact info.

A good power wash and coat of paint on the outside goes a long way too.You can get estimates from many mobile home-specific contractors that understand these needs if you are not going to do it yourself.Basic repairs on a decent old home can run between $2,500 to $15,000 depending on how bad of shape it's in.

You need to run the numbers on where it will make sense, you can figure 2 months difference in permit delays for both then add the "premium" you'll get for selling a 2016 vs 1920.

If not, run searches on this site.

Since its your first investment, understand it doesn't need to be a home run.  

Most of the surveys I've seen around the Triangle run between $350-$450.

But concealing information to obtain a mortgage runs the risk of becoming a felony (multiple posts on BP about this) and I personally have no interest in that.

many of them are on streets where all the houses are run down...HOwever you can go 1 or 2 streets over and find same style homes, same age etc...that have been reasonably maintained.

Mitigate your risks by doing lower risk deals, being conservative with your estimates, and always running your own numbers.
