The average cost of single family dwellings is around $180,000 with an average residential income of about $48,000.

Just look at it as a learning experience and try not to dwell on it...life is too short to do so and I'm sure you could use that energy on something else that will earn you the money lost PLUS SOME :-)Best of luck to you!

Goal is multiple streams of income!  

It's a single family Dwelling. 

Our company literally can't buy properties fast enough, the demand is way high.The #1 thing I see in our application stream each month is to low or no credit, plus income.

It is a little late now, but If we assume that your property's land value was approximately 20% of the property value at the time of conversion, your depreciation basis for the dwelling structure should have been about $144K, giving you about $26182 total depreciation over the past five years.  

This is a 2 family dwelling.  

It sounds like you have done well to this point and are now looking to move forward into a more passive income stream.

Juxtapose that with having an SFR, if you make that same mistake you don't have 4 other (small) streams of income to make up for the one that's missing. 

However, in the case of Residential Lenders ( 1 to 4 unit dwellings) it's exactly the opposite: For Conventional Conforming loans, the Agencies (Fannie Mae, Freddie Mac) will not allow you to vest in legal entities.
