@Jennifer Brown Im an aspiring investor looking for motivated people in the Valdosta area to collaborate and network with.

There are a lot of tools/resources out there which can help with tenant screening and the new laws can make some of it confusing (admittedly I'm not based in NY nor am I a lawyer who is well-versed in some of these new NY laws). 

Of course folding, sealing, and adding postage would be quite labor-intensive, but I think I might also have access to a folding machine, and in any case those are the sorts of tasks I don't mind doing while watching TV or something.I've done some research and think I have a decent understanding of how to get bulk mail rates with folded self-mailers, and how to save even more on fees by adding a barcode (probably by using the free USPS IMsb tool?)

Without that knowledge, I will not know what is a good deal despite the powerful tools that BP has. 

c) A twist on b is to just look up the info in your county's foreclosure search tool. 

Mailing post cards is expensive and not nearly as cost effective per deal as SMS nor as fast a response.Other tools that I have looked at and terse comments.

If you're handing out hundreds of thousands of loans to folks with below average financial literacy, i/o is a bad thing (& this is why HELOCs are harder to get than Fannie 30YF amortized).If you are a specific borrower, and financially literate, i/o is actually a good thing (there are full doc A-paper i/o 30YF mortgages, but not from Fannie, and harder to get).Interest only is just a tool.

What tools do you BP folks use to analyze short term market rentals?

They use it to entice and advertise, it's a marketing tool.
