Sure at 10 doors that might be easy, but at 100, having even a quarter of your door count dictating how you run your business as opposed to 100% of the doors you manage follow the same process is going to hurt your margin and make it so your margin looks like its at 75 doors anyway.

I have personally set a goal to buy a rental property each quarter this year.

I looked at reviews and they are pretty back and fourth, more good reviews than bad but I wanted to see if anyone on here has any personal reviews in regards to the cash buyers list on the website and if it has helped them.

With the first three quarters completed, we anticipate having less than 20% of our portfolio experience a vacancy for the 6th year in row.  

Sham contracts are not contracts, which means you run the risk of assigning a "contract" to a third party while the seller sells to a fourth party, and defends his action on the grounds that you never entered into a contract to purchase.

Kent MI for example, home to Grand Rapids, charges a quarter per record per year, and this is before they get filtered by amount owed and years delinquent.

Sometimes these end up in our municipal court system with them being charged with a fourth-degree misdemeanor.

We were mistakenly given an upstairs unit one time immediately after I had a baby (she was like two weeks old, and our fourth child so we had an 18mo also, and the concrete stairs gave me the absolute worst anxiety) so I agree that a three story walkup won’t be agreeable to her after a few months and she might want to leave anyway. 

Quarterly I am honestly not so sure about but like I said in my OP, I am open to suggestions. 

You must have some sort of secondary egress if there is a living quarters -- either a door or an egress window.There is pretty standard wording in P&S agreements that all work has been properly permitted.
