Generally speaking, you're paying for this feature in the form of higher-than-market interest rates, and interest-accruing balances that are not often paid down. with FHA allowing for 3.5% down, conventional allowing for 5% down (and 3% down in some cases as well), the barrier to entry is not massive. if my mother were asking these questions, this is what i would advise her. small down payment, but a significantly better loan IMO. hope this was helpful! 

We're going to live in the 1/1 500 sqft mother in laws and airbnb the 2/2 1200 sqft main house. 

My mother is hunkered down right now in my STR in Four Corners which is about to get hit.

My tenant’s mother recently suffered a stroke.

This is via my mothers home that my sister and I inherited.

The home is completely paid for no mortgage exists and he had received the home from his mother in law and been in family for 20 years plus.Any concerns I am not aware of with changing title via quit claim?

There are multiple cities basically in the city of Columbus with higher quality school systems and equally high property taxes...Westerville, Worthington, Dublin, Bexley, and Grandview Heights are all "in" Columbus, but they are their own cities...taxes in these locations on a $300k property will run $7-12k/yr.The asset you are describing is not going to pencil out very well...what I mean is that a $300k property in one of these locations is not going to rent for $3,000/mo...maybe not even for $2,000/mo...there is a definite sweet spot here and for SFR it is between $135-175,000....nothing fancy...lower taxes and much better ROI across the board.

Her mother still lives at the house we’re buying and we want her to continue living there for many reasons, but a big reason being that we employ her as a nanny.  

My current property has a 9% CoC and a $1,000 Cash flow (SFH with mother in law).

The house is from my step mother and she used to rent it out for years but doesn’t want to deal with it.
