Secondly, the homeowner would need to cooperate as she would need to submit a bunch of paperwork including income statements, tax returns, etc. for the Short Sale application to show that she is insolvent.  

Finally, even as the landlords cash flow increases, depreciation should keep a major portion tax deferred. 

But weigh the costs of insurance and taxes against the cash flow and make your decision accordingly.

Other advice, especially that pertaining to tax benefits, is also highly appreciated!

The homeowner has direct title, can sell at any time and gets 100% of the appreciation and tax benefits on these houses.

Finally, check with the Town to make sure there are no municipal liens, Make sure they're on Town sewer, check with the tax assessor to see how many bedrooms the tax office thinks there are, (important if you are flipping) buy ok to have more bedrooms if you are planning to buy and hold.  

@Megan HerringtonBigger Pockets is a great place to find a real estate tax accountant. 

And i found launch control but the minimum is $500 a month, but they use cross-referencing data across sources to find the most accurate contact information by using a person's name and address to find their phone number, real address and email by accessing public databases, phone number directories, credit reports, utility bils, public tax records, and social media profiles. this is waaay expensive for me as a beginner. what do you suggest or if anyone has any suggestion I'd greatly appreciate it.??

It can be done ethically, but you need safeguards to confirm mortgage & possibly property tax payments made on-time, as well as insurance with you protected.- Also, you need a legal way to take back the deed if buyer defaults!

Don’t forgot to look at all the ways properties make money: Appreciation (#1 way), equity gain through principle pay down, tax benefits, positive cash flow (never as much of a wealth-builder as appreciation is in good markets).
