When Lenders are considering you for a loan, they typically will look at your income (reported on your last 2 years tax returns) along with your recurring monthly debts and credit score.

Can you make the rent payment electronically on a recurring basis on time?

Some recurring advice I've seen in the "Intro to REI" videos and in the forums is to be conservative when estimating expenses, and I'm finding that makes it difficult to make any property cash flow, especially if I'm living in one of the units.For example, this fourplex: https://www.zillow.com/homedet... is only 250k (which is so much lower than most other fourplexes I've seen that it seems like there might be some additional due diligence required).

My goal is to buy investment properties on a recurring basis. 

@David Ruskey, does your wife have a recurring income?  

Are there any hidden or recurring fees that I should know about?

In other words, is that a recurring expense, or is it one time?

I would do a couple things.I would renegotiate the sales price to include seller contribution of up to 4% of the non-recurring closing costs. 

I had one who setup recurring payments through the end of the year and forgot to extend.

They chagre ZERO recurring fees like other places do, only a one time set up and reg management.They not only manage the property as you would exspect but also seek ways to imporve value and cashflow.
