I’m not sure I understand the question, but regardless with proposed rents or income, and an asking price I can run estimates and tell you the dscr directionally.

Map, current zoning, proposed zoning, plans, any applicable studies, may need a notice requirement for public hearing for all owners within a radius, but any lawyer can help with this, or just call the city as noted above.

And I hounded the GP to propose terms sooner rather than trying to leave it to the end.

However, legislating AirBNB out of business is a serious issue.Major tourist cities tend to be dominated by the political left.

He walked property with me and provided assurance I needed to put in a quick offer without taking excessive time to evaluate area I'm not versed in or try and hire a contractor to walk property with me.My partner proposed that I get an annual 7% return on my down payment off the top of the net cash flows and retain 100% of the initial equity from down payment and then we split the remaining cash flows and equity gain 50:50.To me this almost emulates a 3 party deal with a money man (7% annual return interest only off top) , a real estate investor (50% equity gain and 50% remaining cash flow) , and a contractor/repair man (50% equity gain and 50% remaining cash flow) except that I take on the role of the money man and the real estate investor. 

How do I go about making an offer for 52k and have the seller finance 17k, also what terms should propose?

Meanwhile, another investor who knows my situation has proposed that they renovate it at their expense as a joint venture partner.

I have heard of people that have challenged those proposed rules by the county and won.

@Thomas S. what you are proposing with the idea of raising rents or ending a month to month agreement is illegal discrimination.

If they reject your proposal then you'll have to honor their agreement and wait for them to leave.
