Do a search...this comes up regularly.

Identify the best route for financing by speaking to 4-5 different lenders (potentailly use FHA insured loan to maximize levergae).

Unfortunately, the police will not get involved - you will have to go the eviction route naming the tenants and all "John Does" living on the property and only have you get the eviction order, will the sheriff get involved to help with the lock out - the process takes time and especially with Covid, tenants have a lot of safety nets.

If I went this route I could charge it under my lease agreement as additional rent due immediately and charge 75 service fee.

I had trouble just doing DoorDash shifts regularly after I got my license because of how much time I spend on other aspects of my sales agent biz.
