a lot of successful investors I know and have spoken with have not done incredibly sexy strategies that seem to blow me away.

The investor's theory behind his suggestion was to use the 500k loan to wipe all debt and only pay on the new loan, I'm not sure if this would be advantageous financially due to my current debts monthly payments set at: LTR = 1900MTR = 1500HELOC= 550Vehicle = 850Total = 4800 monthly At current loan rates for 500k, and a 800+ credit score be a lower monthly than the $4800?

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

Credit score and experience level are the key factors to how much leverage we can provide you. the standard is 80% of purchase and 100% of rehab and those deals are the easiest and fastest to get funded.

Lender had access to my savings account, DTI, credit scores, etc.I put 3% down and used the rest of my savings for the rehab.

It’s incredible to see how far you’ve come since starting here 10 years ago—200 houses and 60 in one year is no small feat!

Realistically I believe this means that if you use a service on-time payments will help the tenant with credit scores but late payments won't hurt as they can opt out if they start to make late payments.
