And then it will cost you a lot of time and effort to compensate the loss of income.

What you brought in as a rental, especially a STR or MTR probably doesn’t matter. 90% chance your buyer will be an owner occupant, so they don’t care.Your account/history follows you, not the property. 

Any income generated from the property, such as rental income, must be deposited into the Solo401K account, and all expenses associated with the property, such as property taxes and repairs, must be paid from the Solo401K funds.

A lot of people in this area are commuters, which means their income isn't tied to the fate of the coal industry.

The income from the property more than covers the bank financed mortgage and the repayment of the down payment to the seller which I proposed to make monthly payments on. 

My debt/income ratio is lower than it really is because I own alot of rentals so for tax purposes and depreciation, my taxes dont show the whole real picture.  

@Steven Schafer don't fall for those tenant negative stories about PMCs.A significant portion of these tenants are really complaining about being held accountable to the terms of their lease!

I think it depends on goals and experience, section 8 is a good guaranteed income, air bnb or short term will have higher rents but you will have more monthly expenses (cleaning, internet, lawncare) student housing is another option, and then good old LTR.

Solid market for low income investors, cash flow investors, Section 8 investors, that type of thing.

Just my opinion but one residential property per LLC is an overkill in my mind and just ends up costing a lot more money down the road in administrative / accounting fees.
