Selling is an option, but since I prefer buy hold over flip, I’d like to compare selling to equity tapping.

Otherwise, simply compare rates, points, term, etc, and make a decision.

Also since your investor is a member of the LLC they can be on the checking account and watch the money in real time this is a critical aspect of my companies.. and I don't have to make up reports etc.. they watch the business in real time … compared to if you have multiple investors and they are relying on your in house accounting and they are not on the checking account ( this mainly from the investors side of the table this is were things go sideways for investors.) no real access to the ACTUAL checking account only reports made up by the sponsor.. 

@Jay Hinrichs I believe anyone trying to sell their home can go on Zillow and receive and compare instant cash offers from investors, like invitation homes, etc. 

The rewards will depend on the deals you make. you could make more either way you go depending on our DEAL.Deal's are where you make the money.

How does it compare to the other apartment complexes in the area?

Also, when a buyer was buying single family home there would ask for a comp-based appraisal and a single family comparable rent schedule Fannie Mae Form 1007/Freddie Mac Form 1000. 

Look for borderlines, where the ghetto morphs into a comparatively nice street of houses, and figure out what anchors that area.

An example is if you are worth 10 million but buying something for 1 million and it doesn't work out the way you hoped but you take a 200k loss to get rid of it then it is not good but not the end of the world and you learned.If you are worth say 1.4 million buying something at 1 million and it goes bad the repercussions can be felt a lot more and your risk/reward factor goes up considerably.

I have found that oddly this can lead to an even greater financial reward for the simple reason that you may not have that much competition to deal with as a real estate investor, plus you will find that in places like Erie, which by the way I have also invested in, you might find some great hidden gems in what appears to be nothing but rubble.
