If you decide they're not a good fit, then vacate them and release with new tenants that you actually correctly screen and lease to. 

I just write the property address on the receipt.I couldn't fit a different credit card for each property in my wallet.

Something else to consider is that once these properties are paid off, you could cross collateralize to purchase additional properties that fit your buy box so that you may not need to bring cash to the table for a down payment.

The tenants just moved in, and they're responsible for their own washer install, but their installer refused because the drain pan was slightly the wrong fit.

As a manager of over 20 units, it's important for me to have a software that fits the needs of the properties I own and manage for others.

@Heidi Fahringer wasted time doing several calls and then a meeting with a CPA and then got shocked with their proposed fee.After even more wasted time trying to find out from them why the fee was 10x what I had been paying - a lightbulb in my head finally lit up and I asked the revealing question and found they had a minimum charge.Obviously, we were not a fit.

Do your research and get referrals from people you trust to find the right fit for you.

I’ll also add that it could be an especially good fit for you given that you’re primarily after cash flow.The other options you list—land, multifamily, commercial real estate, etc.

You don't have to tweak much to take a traditional LTR lease and make it fit an MTR or month-to-month setup.
