We wouldn’t want to resell within a year for the reason you mentioned, but we’re starting to think it’s a smarter strategy to buy and quickly fix up a duplex or more to first get our foot in the door.

have a rental next door to your SFH would likely mean being next to a delapidate SFH.The aids health foundation has spent over $40m trying to get this to pass.  

But they never do, or will.

However the thermostat is mounted  to the wall a few feet from the front door in a highly accessed retail store where the door is constantly opened.

Now if your interpretation is cash flowing enough to quit your job that is another conversation.  20 or 30 properties at 1k a month a door, if managed properly is a great revenue mark in my book. 

You'll need at least 125-150 doors to make a decent living, but you won't be able to afford much help. 

This is my way of not being forced to rent to the first qualifying party that gets a toe in the door.

While I do take into consideration all the relevant expenses when I vet a property I still like to see at least $200/door cash flow so I can more easily build up my reserves and have some money to work with.  

I have about 4 doors here in Columbus, Ohio in Hungarian Village and Southern Orchards that are renting about $1375 a unit for 3 bed/1 baths.

I personally would rather a few properties make up a sizable chunk of my net worth vs. 100 doors that appreciate a thousand a year.
