What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Leveraging a HELOC (home equity line of credit) could allow you to invest in multifamily without completely draining your savings.

Cards and board games for older kids but they will all have tablets or phones unfortunately. 

The only example I can think of is that I asked an applicant questions about their credit report.

We consider background checks and credit checks only good for 60 days. 

But I'm guessing maybe your credit is too low for that?  

Quote from @Charles Fay: Hello all, first time posting and wanted to ask for your advice.currently in the military awaiting a 9-12 deployment within the next 6 months.I will have ~150k savings after deployment, 85k before, with no debt, payments or anything other than basic bills, 750+ credit.

I could be misunderstanding how this deal was structured, but wouldn't the seller who is on the underlying mortgage have an incentive not to let it go into foreclosure since their credit is at stake?

Also, townhomes are a great bridge property, it's a common trend that those in townhomes are aspiring for home ownership meaning credit sensitive and with that right mindset. 

At this point, I would recommend having a line of credit to cover these things so you don't have money sitting in the bank doing nothing when it could be put to work.I have 33 units, no debt except for mortgages, and excellent income.
