Would you go to an inexperienced doctor because they had fewer patients and it was easier to get an appointment with them?

I don't round the corners on my countertops, I don't place the matches on the top shelf where they are out of reach of children, and I don't warn them about the dangers of microwaving children.I'm pretty sure every American has heard about hand washing a thousand times over by now.

I recommend a Post Compliance Assessment Determination (PCAD) every 5 years or so.Here's the law (emphasis added by me):460.100: Duty of Owner(s) of Residential Premises (B) Whenever any residential premises containing dangerous levels of lead in paint, plaster or other accessible structural material undergoes a change of ownership and as a result a child younger than six years old will become or will continue to be a resident therein, the new owner shall have 90 days after becoming the owner to obtain a Letter of Full Compliance or a Letter of Interim Control, except that if a child younger than six years old who is lead poisoned resides therein, the owner shall not be eligible for interim control, unless the Director grants a waiver pursuant to 105 CMR 460.100(A)(3).

I think fewer units with more upside is the way to go... even if it takes a year to bring rents to market rate and turn over tenants.   

You definitely do get fewer leads for more time.I think that Driving for Dollars does give you leads that are more likely to sell though.

Banks lending commercial funds for mutlifamily acquisitions have fewer restrictions on the situation with your W-2.Otherwise stretch your money by marketing for distressed sellers.

Living off a loan is expensive and in my mind also dangerous as you bet your livelihood on the success of the project. 

The danger here is that the lender can technically call the note due (Alienation Clause), but I have not actually heard of this ever happening. 

Family situations can get messy, that’s why domestic calls are some of most dangerous.

The larger the project, the fewer buyers are available, and therefore you need to be more selective in the markets you pick, before drilling down to properties and the submarkets.
