I have been doing a lot of research about the new 506(c) third party verification services of late.

I had to stop going to school out of panic that tuition would get in the way of me paying the car (as I was constantly being reminded that a voluntary repo would kill my financial future, my chances of purchasing a home, and make it more difficult for me to get approved for student loans etc) I ended up trying to to keep up with payments. 

How much will the credit score drop when pulled for tenant verification purposes?

Obtaining a verification of employment, deposit, credit report as well as other documents will establish a loan file.

But the basic answer is my selling point is school district, and I would drop as much as I had to to get a tenant in August rather than wait till after the school year has started, or especially winter.So, on that applicant that only wants it for a year, isn't it a case of possible vacancy a year from now versus certain vacancy now?  

No, without a ton in advance and verification of employment for both

@Arthur Banks I tried to use rentapllication.net for checks but I had to go through this entire verification process and send in all this documentation on my business just to do tenant screening.

There are some caveats; however, that is why someone like myself networks with colleagues worldwide in an effort to to be able to research and get things done.

Yes, its very common for apartment complex's and such to require atleast the deposit to be verifable funds, cashiers check, money order, ect.

especially when you can buy more houses subject-to with really cheap debt.I certainly would not consider buying subject-to to be locking in today's low rates.
