Sell a property or another passive investment.While options B,C,D may allow you to "cash" your losses, you could be shooting yourself in the foot.

It is true that you may miss out on this home, if sold this week, but also consider the Joy Of Missing Out (JOMO) by not overpaying for this property and also footing the bill for many of the potential repairs required for a 120+ year old home as mentioned above by the previous commentors.I would encourage you to take a contractor with you to the open house or someone with experience in this age of home to give you some insight into the property and what may need to be addressed in the first few years of ownership. 

The 770,603-square-foot, 10-building portfolio traded for $144.5 million, or $188/SF, at a 6.25% cap rate.

Say 20x30 10 foot roll up door and a walk through door?

Title company defended and it took the attorney they hired and myself 3 years of lawsuit with neighbor and dealing with the state of Oregon to get the right of USE across an old logging railroad easement the state bought for a linear park.

The first house I bought was a 1,500 square foot house with fenced in yard on corner lot.

But a good place to start is by figuring out what a rough price per square foot cost would be in your area for a unit turn, cosmetic, and full gut renovation.Here in Chicago unit turn might run $15-25/SF, Cosemtic $45-65. and full renovation $90-$110 of interior renovations only.Hopefully this at least steers you in the right direction.

The reason you are seeing a wide range per foot of sale price is because there are hundreds of variables in NNN properties.

I talked to an appraiser who would put flat land around $100 a Sq foot.

Furthermore, the property sits on a nearly 6,000-square-foot lot.
