@Robert Ok you can go to Zillow, enter the address of any 4-unit and see Zillow's history of the value and rents.Future rent growth is only a guess - much like trying to predict the future price of a stock.Vacancy/Absorption will be difficult to get just for 2-4 unit properties - the local real estate board might have it for ALL rentals. 

See the chart from Fair Isaac Company (FICO) below: FICO Score Pct of Population Default Probability 800 or more 13.00% 1.00% 750-799 27.00% 1.00% 700-749 18.00% 4.40% 650-699 15.00% 8.90% 600-649 12.00% 15.80% 550-599 8.00% 22.50% 500-549 5.00% 28.40% Less than 499 2.00% 41.00% Source: Fair Isaac CompanyAccording to this chart, investors should use corresponding vacancy + tenant-nonperformance factors of approximately 5% for Class A rentals, 10% for Class B and 20% for Class C.To address Class C payment challenges, many industry "experts" are now selling programs to newbie investors about how Section 8 tenants are the cure.

Realistically, you will probably only get the deposit amount back, but you should itemize the cost to get it rent ready and the rent for the period they should have given notice and put that on a move out deposit itemization.If you don't have a forwarding address mail it to the address of the unit. 

Another thing is QC will penetrate re-used addresses-- meaning if you're doing isolated withdrawals or single address one's--way less at risk.

Is there a reliable app or software that you can just enter the subject address and it takes all the guess work out and produces accurate comps? 

We need one that finds correct mailing addresses for our leads who have not submitted a change of address to the post office.

Most of the time a mailing address is provided, further Google search or private data bases may uncover phone or email. 

Sellers need to price competitively, prepare their homes carefully, and address potential concerns before listing.

Although these are not trust or will, they will gum up the estate closure so these need to be addressed.
