I personally invest in the North Dallas area (Prosper/Celina) where there is lots of growth in homes with nice lots.

You could do something like what you want if it was your personal primary residence and even then the interest rate would be ugly. 

what kind of investment was/is this  a little more detail may protect others if you think this person is a financial predator.  

The properties in OK, which are roughly 30-40% smaller than my personal residence are only about $400-$600 cheaper than my FL insurance.

I lived there from 2017 to 2022 and personally witnessed significant changes during that time.

I will caution you that if they pull something like this and you immediately start offering any concessions as is repeatedly addressed above - this type of personality will make note of that and the threats will be ongoing for the duration of their tenancy.

That could be a PM or you can hire a person to work full time for you. 

It depends on where you want to live, income, personality, and other factors.You could buy a large home and rent out the individual rooms to cover expenses, but this comes with problems.

If it was me personally, I would not.

So why is the $2,500mnth person paying $250 and the other one paying $350 ??????
