I proposed a mutually beneficial short term partnership.  

Any advice on best ways to structuring proposals to investors?

I ended up proposing this to the wholesaler:They allow me to have a purchase contract directly with the current owner BUT I give them a courthouse recorded note or lien for their fee.

LTV or Loan to Value: Proposed loan amount divided by the value of the property.

I would hire the architect first to put together a brief proposal for the city.

I note you are in the COLA, is the site zoned correctly for your proposed use?

Hard to believe perhaps, but a Philadelphia City Council member has proposed something to deal with this:http://www.phillymag.com/news/2017/09/29/councilma...

I said I was flying back home the day after and would like a proposal ASAP.

Options our lender proposed if that didn't work out was 30% down 15yr non owner occupied financing + 6mo reserves until vacant and then refinance to owner occupied which we were prepared to do but the former option worked out.

The STR rules being proposed in San Diego really favor owner occupied.
