I am not 100% sure if what you're proposing is realistic as you already own the properties but the lenders can answer that question for sure.

@Rayan FarisI get the altruistic intention behind your proposal but I just have this gnawing feeling that this may blow up in your face some way, some how.

With HomePossible and FHA, you can use proposed net rental income from the smallest 3 units to help you qualify, as long as you will occupy one of the units as a primary residence. 

The seller stated to me the asking price and requirement of me to submit a Purchase Proposal so he/she can have an idea of economics before sending me any current lease information.Just curious to know what exactly the seller is asking me to include in this Purchase Proposal...?

Form should have come in the same letter notifying you of the Tax Appraisal District proposed Tax Value for the current year.

Is it possible to propose a seller financing option to a buyer with a property you have under contract from a wholesale deal?

I think I've seen you on the Facebook page for the Colorado Springs Short-Term Rental Alliance, so I know you already know of the proposed ordinance down there.

The main issue that you'll run into with what you've proposed is that you cannot legally rent out 4 rooms separately in Philadelphia.

It gives you a decent ballpark for what certain things might run.Just make sure that anytime these companies are willing to speak with you and help you out, the day you have the keys, make them the first call for a proposal.

Nothing in the post mentioned what the balance owed is - just the amount to stop the foreclosure which could just be the arrears.My guess is that the monthly mortgage payment was less than the amount they proposed as rent; if they couldn't make that amount of payment while THEY owned it, what makes you think they will pay that every month when YOU own it?
