For us, the visibility seemed worth using both platforms. 

It seems this market is ideal for cash flow, as rents seem to easily cover mortgage, taxes, and more with plenty left over for profit.

With current interest rates though and cost of property in Nashville, nothing even comes close to seeming like it will rent for enough to offset what our monthly payment would be.

Although this might seem like a super exciting way to “get out” of your current situation, please understand that REI is a very competitive and difficult business.

Obviously, if its stressful, unnerving, whatever, then sell.This doesn't seem to be your investing strategy so you don't have to scale up. 

Seems like a good value add type item if it's scaring other buyers off, leading you to get a better deal on it.

At first I had a hard time trusting -- the prices it set for high-demand periods seemed impossibly high, and the prices for low demand shoulder seasons seemed way too low. 

If the rent coming in from the tenant (not coming out of my pocket) is more than enough to cover that monthly debt payment, that seems to be a benefit to me.For example (purely made up numbers), purchase a property for $100K. 

.- Maintenance: They offer minor maintenance in-house, with the markup fee applying to expenses over $300.Do these terms seem reasonable to you?

Buying a fixer seems unreasonable given I have a day job.
