We had left over lumber already on hand to use for the fence bracing and 1 80lb bag of concrete so that reduced our costs to just 9 fence posts, 6 50lb bags of concrete, the rental of the post hole digger and some stakes.

Look around for a supplier Trying to unload mass amounts for cheap.

When you see a semi loaded with porta potties unloading at an industry or some other place where there can be an event or gathering, it means there are going to be lots and lots of people coming in the near future. 

The current owner appears to be the builder and they are ready to unload this deal.  

It could be an apartment building or an investor looking to unload their portfolio of single-family rentals. 

There are tenants on it as well and making almost 400 usd after mortgage payment.I do not need the cash but I am worries about the capital gains if I don’t unload it soon.

Lumber industry stopped using bleach, now FEMA has stopped recommending it except in flood emergencies where bleach better than nothing. 

If you know you are going to unload it in a few years you could also try for an interest only 5/1 ARM or something, which would boost your cashflow but leave you with no equity paydown.

Let me know if you need more info.Here are the options, I see:1) If no reasonable offers, let new home contingency fall through and shop for home in the spring AFTER selling ours2) Buy new home and keep ours as a long-term rental (will be tight on cash, but could make it work)3) Drop our current list price to just unload the house (we'd still make money since we bought at the bottom of the market) and buy new house4) Go forward with buying new house and agree to the contingent offer of 418K mentioned about. 

Flippers are probably picking up these "deals" and then getting burned on properties they cannot unload.
