These markets are revolving doors with properties being resold every 2-3 years to new green investors looking for cash flow, who don't realize what it costs to maintain a property or that their budget of $50/month for maintenance, repairs and capex is not nearly enough ($300-500 is more like it, that's why rents under $1,500/door typically have no margin for error).

The fact that I didn't really reside in the properties I invested in taught me my lesson quickly.It's inevitable; we all make errors.

I am always open to talk about the do's and don’ts to help avoid up front errors.

@Cleva Heffa looks like we have both co-founders of OfferMarket here on this thread :) One of our clients was just featured on the Bigger Pockets Real Estate Rookie podcast and he speaks about his experience with OfferMarket for his DSCR loans: https://www.biggerpockets.com/blog/rookie-381

It's really trial and error on pricing.

I’m not sure how to go about it I’m a rookie at this and bought my first 4 unit apartment 

Highball all your numbers and leave room for error and unexpected expenses.

Well, you have have made the same grave error by signing a HAP agreement with HUD without reading it. 

And a sure way to make nothing or lose.. you may make the 10k but that's a razor thin margin and no room for error taking on a ton of liability and risk for very little return.

However, I can't tell you how many clients come to me having used Turbotax and they either had errors on their returns or missed out on thousands of tax savings.
