Spending as little time on each door as possible.  

Hey Abass, I was raised here in Columbus, Ohio and have 4 doors here.

I don't think we will ever have enough "doors" to replace an income in this time frame, but we would like to get to 5 doors in the next 5 years which we would sell in 10-15 years to help supplement our retirement income.  

House hacking a duplex is a great way to start scaling your portfolio to more doors.

Owning 25 doors, I interview all my tenants, just like a job interview.

I'm skeptical. in most markets section 8 only allows one year leases.. and in my experience with 200 plus section 8 doors tenants move every 18 months they trash one house then go find another freshly rehabbed one.. of course each market will be different..

I have a nice hi-rise condo unit and I get tons of companies asking if I do MTRs for Visiting Nurses, Tech Professionals, etc.My place is positioned near a number of large DC Metro Hospitals, but since covid work-from-home and recent lift of Eviction Moritorium, I have had few people with jobs, but a ton of people recently evicted looking to rent my place.The one viable group - visiting nurses has been excluded because my HOA will not allow short or mid-term rentals (anything less than one year is a No-No).They claim too many transient tenants cause excessive wear and tear on the property and too many people using resources like the gym, or pool or common areas.I think that's a lot of horse waste!

My clients with hundreds of doors use data to cull out the lowest performers and give someone else a shot at making them more profitable.

Your only recourse on the PM would be if you could prove they did something grossly negligent, like leaving the doors open. 

House goes into LLC, but if you still have leases outstanding signed by you personally, that can open the door to maintain personal liability.
