I can pay utilities, insurance, and other holding fees but I won't have enough to pay other cost like listed above.

The rental income from the first home will pay for the mortgage/monthly costs.  

If they failed to pay the bill and utilities are shut off, they are responsible for any damages caused.

I would also pay by activity not by the hour.  

Rewey: Your Comment: "the ultimate solution is to pay it off if it gets called due."

He knows the loan will pay and they won't default because he knows they're solid. 

As we all know, you are really paying for the commission in the purchase price. 

So that with paying my investor 6.3%, they will get a passive income of $2,532 every month ($30,384 every year).

All rents you get from this property has to go back into the SDIRA but if you get a 20 year mortgage (that the rent can cover) and can pay the rental off by age 65 you will have turned that $90K into several hundred thousand’s of paid off real estate.

Quote from @Edgar Duarte: hi allI would love to get some perspective from your expertise, we have a property that we would have to sell in 2025 to avoid paying taxes on the capital gains, we believe we rcan sell it for $700K and get an equity of almost $500K after paying the mortgage balance, if we invest all of it option in index funds at 7% rate (standard com growth calculator), or in more rental properties as we are all here for, I can get the equity of around $900K.option B would be keep paying the house at 2.3% int rate while we have it in AirBnB and maybe sell it in 10 years for $900K, knowing that we would be paying taxes but it is not that bad still. or we can 1031 at that point?
