You’re all set just the way it is.

Also, don't take the funds up front, make draws as you go.

I am responding as a consumer not a STR owner we had one its lasted for us for exactly one tenant then we felt it was too much work for the return  on investment we do much better loaning money and buidling new homes than to worry about people goofing up our homes :)I do have some MTR you know fully furnished homes in Vegas and those are money makers for us top of the line tneants paying double the going rate for rent.

Most lending is based on cashflow, not the 2% rule (although still a good rule of thumb for some types of investments), might have the most help from the group if you provided some of those details here just so it'd be easier for us to help you best. 

The tenant in common nature of the ownership would tell me that you would only be related to your mother in laws portion at the most. 

I wouldn't touch anything outside the urban core. if your strategy is to buy existing and old I'd recommend not to. as a newer investor depending on your liquidity look at build to rent development. building investment properties below market value by 25% and refinancing out of it to do it again. the urban core has tax abatements as well that are 15 years right now you can apply for. that means that taxes will be around $600 to $800 per year. there's cash Flow but the existing inventory market dried up a few years ago in the urban core. local realtors are going to push you to the trash areas like hilltop, south linden, etc because it's the only place numbers work. columbus is great, but remember a tenant who pays $1800 a month is different than a tenant who pays $900 a month. let me know if I can help any other way! 

This allows me to pay off the private loan (~$550K principal + $49,500 interest).

This ties up the veteran’s eligibility, which can have long-term consequences for them.

Looking forward to exploring the area and looking for more investments around the area.

Just sitting on that rate for the life of the loan?
