Complicated scenario I have no guesses for best tactic:  dual/final death:  all 401ks are distributed upon death. 

Purchase price: $125,000 Cash invested: $85,000 Started off as a run down outdated 1 bedroom 1 bath home in Sanger - was purchased from a wholesaler for $125k - Added 1 full bedroom to the house, replaced wall heaters and window AC with HVAC ands ducting throughout - replaced old circuit breaker panel with new updated one and rewired interior electrical, replaced all windows with dual pane windows, replaced most of the doors, laid new carpeting in the bedrooms and wood plank flooring in the living room, tile in kitchen and bath, added new baseboards and painted interior, replaced all doors in the house, granite countertops, new lower cabinets, all new appliances, added rails to the front porch, converted an older closet into a laundry room / new closet, completely remodeled bathroom to make way for a new door to the new bedroom ( not shown in pics), new wall tile in tub/shower, redid some roofing, and painted the entire exterior.

You can buy some dual-head mini-split units but the cost is going to go up dramatically.

To make it worth my while to even do this, I would really need to have both sides of the commission with a dual agency.

The obvious ones are saving them the hassle of listing, and saving them money on agent commission if they choose not to get an agent; but I am sure there are other creative suggestions out there.Is it pretty common for the buyers agent to act as a dual agent in situations like this?

You can also make it clear to your agent that you don't want them to be a dual agent in this transaction that you only want them to represent you. 

Hi,I'm a dual citizen, Canada and USA. 

Their dual master units were nicer.

The agent JUST sent over the sales contract&dual agency agreement last night.
