If you don’t mind me asking, Do you have a specific letter you mail out or is it a generic letter asking to buy they’re property? 

The comment was based on a desk review of a couple places within 4-5 blocks of John Hopkins Medical Center.  

These might include Owners with Low Financial Stability Scores (FSS) or Seniors with Long-Time Ownership.Make sure your letter addresses the difficulties of selling a home the traditional way.

The ideas and drive is there to find the deals...im ready to start letter writing campaigns, sign campaigns and searching hard to "buy right" with the ultimate goal of performing BRRRs.

I have heard a lot of good things about yellowletters .com and they can send letters to lists that you specify your parameters for them. 

If you delead, and maintain the standard, you will be in the clear.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).

The quality of rental and housing jumps drastically from block-to-block and neighborhood by neighborhood. 

Every city it seems has a huge change in values block by block and the cheap houses are cheap for a reason.

It would probably be worth trying it on Airbnb with some furnishings as that way you can block off the days that you want to use it. 

Much of the city is very block by block and its a good idea to take a look at the home values in different areas as well as the proportion of owning vs. renting in different sections of town.
