I feel like it could even promote me to never have to tell the tenants that I own the "plex" which I also like that idea.

There's a good meet up in Philly tomorrow night I'll be at, but inbox me if you want that info because if I post it here it might get flagged for self promotion because it seems that there's more than a few haters on BP that like to do that.

As you can see, they are not large, but I hope the bath and kitchen will promote retention. 

As with any contract though, you'd need a very specific scope of work, material qualities, etc.

Now here is my two cents - a home's square footage is one thing to compare on a CMA, but there are other things too- updates, materials used etc.

Like a @Brian Burke for example who is a foreclosure expert in your market.. then there probably is not the kind of money in it your thinking there is.picking up the pieces of a failed major rehab can be all sorts of problems.. at least the foreclosure will wipe out material men liens in CA. 

I would post it here, but every time I answer someone's question and point them to the appropriate resource I get flagged somehow by BP for self promotion even though most the resources I suggest have nothing to do with me, then nobody benefits from hearing about the resource but that's BP's loss I guess.

It has been built with several different types of materials, and seems to be held together by caulking.  

You can find all the contractors you need -- just go to Lows or Home Depot 5:30 in the morning and talk to the folks buying material for their next job - negotiate Charles 

When you're ready, here are some good DO's and DON'Ts when getting bids:DOWrite out a detailed scope of work that outlines exactly what you want to do.Clearly define what (if any) materials you will buy and what the GC will supply.Get multiple competing bids.Check GC references, call past clients of theirs and possibly even ask to see their work.Closely analyze each bid and ask a lot of questions on things that are not spelled out.Ask each bidder for an anticipated schedule for the work to be completed.Ask each bidder about their desired payment terms.Sign a contract/written agreement with the successful bidder.DON'TWaste people's time if you're not serious about hiring them.Walk the job with competing bidders at the same time.Assume that all GC's will see the work happening the same way.Pay large sums of money in advance unless it's justified.
