It is fair to give your contractor the cost for the material up front however, do not pay him the labor costs until he is finished.  

But, if there's enough equity here and the amount you need is fairly small then you might find someone to do it.Credit cards?

I'm looking for recommendations for an honest, fairly-priced, and communicative general contractor for handling a few significant repairs.

What percentage of that deal is fair?

Location is fairly good, land is on a major rd and the back part of it connects to an established neighborhood with older brick SFR’s All units a tenant owned, utilities aren’t included and overall condition of the park is on the low end.

I am actually fairly familiar with the O-Zones & O-Funds (at least as much as one can be since Treasury hasn't actually issued guidance yet.)  

Limited monthly cash flow, but maintain good rate of principle reduction at 15K and say appreciation of property at 2% a year.Shortly after joining the Army I was interested in using both retirement accounts (couldn't contribute to TSP then) and real estate to prepare for the future. 

Have a property inspection to make sure mechanicals are properly maintained and in good working order.

The amount of rental income to include in effective income is based on 75 percent of: verified prior rent collected on the units (existing property), or the appraiser’s opinion of the property’s fair monthly rental (proposed construction).

These are the HOAs that collect ~$100 per year to maintain minimal common areas such as neighborhood entrance landscaping.
