Quote from @Chancy Vines: Biggerpockets sells a Lease Agreement Package under "TOOLS" at the top of your screen. $100 for a lease and several other documents, written by investors and attorney approved for your state.

If everything goes according to plan you might make some dollars along the way and a payout when the asset sells.

But that is in line.As mentioned, the cost of finding a new renter for $100 makes zero economic sense. 

If so what's the cost per sqft?

My sister in law wants to sell three sf rentals in Spokane.

Does anyone have experience selling raw land to charities and/or non-profits like Habitat for Humanity? 

Well Don, it depends on the desirability of the asset to other possible buyers (As guessed at by me), as well as if the offer is predetermined to be a lowball offer.Some sellers do not have a lot of ability to go down much and a plethora of buyers may drive the price up above what I think it should sell for . 

(obviously this would be a difficult selling point) I don't see why this would matter since it could finance like a SFH, look like an SFH, built like an SFH, recognized by the city as an SFH, etc.

I'm the buyer offering them the chance to rep me on the buy and the sale once it's built/renovated, so it's an easier sell, but if you can figure out something to benefit both them and you, it should workout

As an investor, I understand there are remodeling budgets that must be met for remodeling, and labor costs can be high.
