not to be a debbie downer but I would not use my primary residence for a heloc and then invest out of state.. especially a C or D class property.. too much risk in my mind  also keep in mind Heloc's can be called or frozen thereby putting you in default and you wont know it until after the fact they are not fully amortized loans.

That is one of my worries of going into a class C or lower area.

Buy 7, sell the lowest two performing ones to pay off the other 5 or trade in for class A properties--lower returns but lower stress and maintenance.   

The big concern I have with this asset class is the control element.

We acquired the deal mostly for the lot, it’s a B class neighborhood in a growing city, on an excellent street. 

Military housing is at high occupancy on-post, making various home displacements more common off-post in hotels or short term rental homes.Small multi-family homes vary in neighborhood types, but the majority of them (but not all) are in a low to middle class area, raising the chances of getting unappreciative or undesirable tenants.As I mentioned earlier, I have no properties and only watch the market for now.

With $80,000, you have an abundance of options to consider as potential asset classes in real estate investing, so at this point I recommend trying to determine your ROI expectations AND your risk tolerance for this $80,000.

Thank you for helping to foster an excellent investing forum environment!

The deals I have seen work are larger 4 units $800k+ in class A/B+ areas mainly as those have less competition and atleast my market noth side chicago they still sell at decent real life cap rates.

Being so, there are some very nice areas, as well as some C/D class neighborhoods.
