Mathematically, you take the expected interest rate and divide it by 72 to get the number of years for your investment to double.

But depending on when you bought your house and your mortgage rate, it might be possible to convert it into an STR with enough cash flow to more than cover the cost of renting another dwelling as your new primary residence. 

We checked out Blue Ridge, GA this week & loved the area but the numbers don’t seem to work at these rates.  

I'd rather not do an entire cash-out refi because I have a much better rate on the property than I could get today.With a 70% LTV planning factor, I'd still have plenty of room for the cash I'm looking for to make the down payment (~125k).Thanks for any help/advice!

Rates are very comparable to conventional. 

The below terms are live as of this date, for a rate and term refi (no cash out).From left to right:Points: 1, 1.25, 2.Prepayment penalty: 10 years, 3 years, 5 years.Commentary/review, hopefully this thought process is useful when evaluating offered terms for a maturing commercial mortgage that needs to be refinanced. 

Also learn to do stress test on your portfolio if something happens (higher interest rate, vacancy, etc).5- Enjoy: You need to love doing that.

Is that market rate?

Obviously, lowering the fee and raising the rate is an option but that feels a little bit like spinning my wheels.At some point, if I'm dropping my rates far enough to compensate for a high cleaning fee, we get into the conversation of "is it even worth it to rent it at this rate and risk property damage, 4 star review, etc".

Go to Etsy and search for "rental property tracker," and you will find hundreds of nice spreadsheets to track 10-20 rentals, usually for under $10.Software has extremely helpful features like online payments, marketing syndication (click a button, and your property is advertised on multiple sites), electronic document review/signing, maintenance tracking, and owner reports.
