That sounds like massive renos (ie new floors, painting...).Yes as you acquire more properties, the chances of having multiple vacancies (no matter how leases are staggered) increases.

My wife and I earn over $350k a year in our jobs and all of that is now going to pay down debt.We have the option to increase our HELOC to unlock some more capital which I'm considering doing to try and get a good return on my money and pay down the debt faster, but given past experiences I'm not convinced it won't end up with more debt.What would you do at this point?

In fact, I have still been increasing my monthly ask with turnover.I agree with what @Dena Puliatti said - it is not a cash flow play in Huntsville right now whatsoever, but more of a "break even" cash flow play for appreciation.Folks, there is a LOT of dysinformation on Bigger Pockets right now about the Huntsville and Madison areas in numerous BP threads right now - more than I have ever seen in the past.

The time back will free up more time to increase your active income, or acquisition of more rentals to get you more cashflow (passively or actively).

How about the increased home insurance cost for a landlord policy?

Can not go wrong with a rental in Ashburn since the rents have increased so much. 

It’s just going to slowing increase with inflation.
