I'm really struggling with the variations I'm seeing in price, though.

I'm seeing quite a bit of variation or no numbers at all and want a realistic estimate.  

Jared, there are state specific contracts, actually many variations of each, for example you may have a standard contract for single family homes, one for duplexes one for multiple units, commercial properties, mobile home, as-is, etc etc etc...then you have various addendums to address specific situations, such as pre 1978 lead paint disclosures, short sale, backup contract, etc etc etc.usually the actual contract you will need is dictated by the nature of the home, the seller, and whatever contingency you may impose.  

I tried a bunch of variations of my listing, some being more explicit about my criteria, but generally wasn't successful in finding people who met my pretty reasonable renting standards.I've since enlisted a few rental agents in the search.

It is usually a direct comps run with slight variations for neighborhoods and school districts.I'm looking at a place right now with an asking price of 40k.  

Future cash flow split 55/45.2) Equity split - other person buys the property with 100% of their funds (or financing) and I am also on title and get 20% on all future cash flow and sale of property.3) Other variations of the above.When partnering on real estate deals, any combination, as long as it's equitable for both partners, and both parties feel it's fair, can make sense.

Though I think that there may be some variations depending on the local PHA.

I am guessing your property is in Florida each state has slight variations on the rule.  

YL,PC,PC,YL or any variation.

I am sure there are several variation of requirements to participate from each county within the state of New York.
