I would focus on the house hack and not take a pay cut.

Use that loan to pay the back taxes and get things under control.

Somebody somewhere had to pay for that real estate at some point and has continued to pay for it since.

It’s paid off, I would “like” to leave it that way & maximize the cash flow while paying down the heloc between the rental & other income.  

Then there you go.One thing I am looking to try to do but haven't done yet is buy something with zero down on seller finance, put the rehab on a 0% credit card, then refi the seller off in 12 months and pay back the card. 

There are quite a number of things that can make utilizing an FHA loan more difficult such as more barriers during appraisal, appearance of low qualification/little cash, typically longer closing period, likely higher interest rate, and PMI cannot be dropped without a refinance if 3.5% down.That said, just chain 5% down conventional loans, and make sure your duplexes pay for themselves.  

Maybe it is ok if it is for you to live there and enjoy the amenities, but no need for you to pay high dues for a tenant to use the pool.Many condos don't qualify for FHA financing in Dallas. 

What if a tenant fails to pay rent, leaves $2,000 in cleaning and repairs, and it takes another month to rent?

@Bonnie Low - it's important to know what services you're paying for.

My experience in Massachusetts, where it took nearly a year to evict a non-paying tenant, has made me more selective about the locations I invest in.I am looking forward to learning and sharing insights with this community!
