You ain't gonna just tweak your spreadsheet a tiny bit and meet with success.

I've been surprised at how much the tiny, little act of giving someone a moment of my time and listening can mean to a person looking for a place.

Charge one of two ways:  A small host annual subscription or a per stay fee that would be a true donation - less a tiny admin fee for maintenance, then provide a guest the option to either match that donation or a force a small minimal amount. 

Example - in my last 2 purchases, I chose tile and/or wooden for all except bedrooms (which were carpeted).

the bedrooms seem tiny if it's just 900 sq. ft. a little overpriced, might not cash flow well.what are the rest of the numbers?

For example, for me, I don't want the majority of my hard money loan portfolio invested in tiny, individual loans that I have to micromanage constantly (because I don't have the time).

Any rent collected would only offset only a tiny bit of the mortgage/upkeep.

It is very tiny and very rough.

If its a personal loan from B to A, the value might be only a tiny faction of the amount lent.

Additionally, considering adding a tiny house to the very large driveway for additional income.
