Slab easier and no water issues like a basement .. maybe less maintenance .. have to rip up concrete to access anything tho right?

Hey @Alba Cheung, I am guessing you have a cleaning team in place, if so, there are low cost, high touch options or high-cost, low touch options.

Sell - Would prefer to avoid this to keep my low interest rate (3.3%) and avoid fees/taxes. 

I’m not sure what his current loan rate is but a year ago probably puts it in a high-fives or low sixes at the most.

Account for repairs, maintenance, cap ex, etc.

If you don't need the 20k for the next couple of months and you have low risk tolerance, it would be safer to use cash.

As for fees, your typical STR management company down here will be in the 15-20% range plus your regular costs to run a STR (consumables, towels, maintenance, etc.).

With a locked-in low mortgage rate of 3.2%, and about $100k in equity after expenses, I'm contemplating my next move.

HUGE time saver.Individual property accounting - keep track of how profitable (or not) each individual property (or unit) is.App for tenants - so they can look at their balance, make payments, report maintenance issues.Rental applications and tenant screening - Accept online rental applications and then run credit, criminal, eviction checks on them easily.Market your vacancies - getting a vacant unit filled with a good tenant as quick as possible is critical, and good software will help you market those vacancies. 

Many investors don’t feel comfortable submitting low offers on homes listed on the open market (MLS).
