Robert,Be aware Dodd-Frank legislation limits the number of owner financing deals you can do in a year.

Juan,Yes, you can use the rental income of the proposed Duplex to qualify for the loan.

Take a look at things like whether the business plan has multiple exit strategies, whether there are signs of conservative underwriting, and double-check whether the proposed business plan makes sense given the asset class, submarket, and current economic cycle.Research market trends in job and population growth.

Remember the Bank sells $$$$ for a living, so clean up your books, write a nice proposal for the funds including what your going to do with it, and how it will add revenue and strengthen the business as a whole, make it very easy to "sell" you $$$$, and they will. 

We made an offer based on the organization's proposed monthly rent.

I actually submitted a proposal thru BP website to one of their suggested listings.

The proposed plan is ~100,000 SQ FT.Thanks for any/all help!

I’ve gone ahead and proposed our offer for owner financing to the seller. $80k on a golf course ($1300 annual HOA).

BUT, you also SHOULD have received a notice about 3-6 months in advance saying this is your proposed tax, you can protects until this date, then they will be written in stone and you will be billed. 

Back to your original question; the city planning department has regular appointment with local developers that propose new construction builds either weekly or bi-weekly(ot sure about your area).
