But what are the expenses? 

I agree with Shawn, while expensive in some areas, it is not saturated for LTRs in Central Florida given the migration data.

Hey Enos, totally can relate with you being from an expensive real estate market - I moved to Columbus a few years ago (from Portland, Oregon which was super expensive) to become a full time real estate investor, and ever since, I've completed quite a lot of BRRRRs, flips, and own a successful rental portfolio here in Columbus Ohio.

Basically financing of 10% is always assumed in our calculations/expenses and if I'm the one who puts up the money I make that 10%.       

So, depending on what you are trying to tease out of those numbers the averages might not give useful conclusions since they won't reflect what is actually going on in any market.

However, if you are using a HELOC to improve a property it can be a great way to keep expenses low and refinance later when rates drop.

An investment interest expense is accrued when money is borrowed to fund an investment.

In Nashville the average is 18-20%, but some people are starting to offer at 10%.

They're saying we have to cover their staff expenses for the rest of the year?
