Lastly, after using the system for a little bit is this really scalable?

It is landlord-friendly, and specific pockets have gone upwards of 2-4x in the last 5-10 years.

So loosing a last name of the partner in the title would not allow me to 1031 I'f the partner cashes out; correct? 

Moving forward--have full photo documentation of the damages and estimates to repair, and have the manager tell the tenants if they cannot pay in full or with weekly payments, (scheduled to be paid off in full BEFORE the last month of the lease) the management company will move forward with legal action.  

Airdna would be beneficial for you to learn the booking lead times of your area, which would help you know when your property is not getting booked or people are just booking last minute.

I just evicted my first tenant last year and had to go through this emotional rollercoaster of not pursuing the money because I knew she simply didn't have it.

Whenever we could add washers/dryers, we would opt to do so.

Demand proof of payment on every unit for the last year.  

This should be a last resort, as it could mean fines or disciplinary actions.

Also if you arent a warning incase you see the taxes paid last year from a primary owner you may have to pay more as you wont have that deduction in property value. https://www.phila.gov/services/property-lots-housing/propert...
