But let's say that the 10 properties are (more or less) cashflow neutral, and now you want to turn that $300k equity gain into cashflow.

A rehabbed home will be very neutral, all new appliances and flooring ect, likely nice but no huge frills.

The dual agent will not act in the best interest of the buyer, and should also not be acting in the best interest of the seller, but be a neutral third party facilitating the deal.

Because we had strong applicants (including you), I actually consulted with a couple of outside landlords to give a neutral opinion.

@Johny Michaud the whole idea behind a BPO is to get a neutral 3rd party opinion so I would say no not on your own property.

With my current job im just above cash flow neutral due to a high New York rent that I'm now locked into.

Frankly, I might consider finding a neutral third party to do an independent audit to look for deficiencies in legal or accounting.  

I understand perfectly well that some of them bring value, some are value neutral and some are value negative.

I spend around 2k a unit for upgrades which include new vanity, replace toilet wax ring and guts, paint bathroom, replace shower/showerheads with low flow water saving ones, paint or stain kitchen cabinets, new laminate counters, tile back splash, paint entire unit a nice neutral gray, and paint all trim white.

I don't care that these are neutral parties and all that.
