I’m no longer house hacking, and all three units are rented out, generating a total of $8,200/month in rental income.

As noted above, up to 50% of gross rental income normally gets eaten up by expenses (taxes, management fees, utilities, landscaping, repairs, capex, etc).

However, you can get loans that are based on the performance of the rental and not your personal income and debt.

If you don't care about income and are more of a capital gain kind of guy, prices are already high (as you noticed) and there's plenty of land available to buy so I'm not sure how much is left in the tank.

The northwest suburbs of Akron are the higher  income areas.  

You have used home equity lines of credit to purchase investment rentals and want to know the best way to pay down the HELOCs.Between the two properties you bought, after expenses, you have $250 a month positive cashflow to use.What I like to do is pay down some principal every month with my positive cashflow.I use my extra active income from real estate commissions helping other investors to pay down the principal even more which just frees up that credit for me to use again.I know I can refinance the HELOC debt before it changes to principal and interest as it is just interest only payments as yours are.One difference is the cashflow, I have greater positive cashflow and could make the principal and interest payment in the future with the extra cashflow I already enjoy.I always get HELOCs on my income properties as well after purchasing them to pull out as much of my downpayment as possible.

It would depend on your income, location and price of the home. 

However, with a SFH you will lower your standards when vacancy arises more than one month as you have no income coming in to male that payment.  

If you have some capital, income, and decent credit, buy a 4-5 bedroom house and rent bedrooms. 

It is disheartening to witness a mentorship program that boasts substantial financial success, with students allegedly earning substantial monthly incomes, yet fails to ensure that their own employees receive even the minimum wage they are entitled to.
