My wife and I have set aside roughly 30k for rehab but we are worried that there might be something really wrong with this house.  

It is half situated on concrete slab and the other half is pretty much built on top of dirt (we think, we are unable to get to it) and I called the building department and there were no permits pulled.How should I go about negotiating down the price?

We are looking for an exit on our property.

They've been on the market for about 6-weeks, in an area where we are seeing less than 1-week on the market, with houses going above market value. 

We are currently building a spec home in Mequon in the 600k range and I would have loved to build at a sub 500k or sub 400k price point, but the between the cost of land, labor and materials it turnes out to be impossible.

Hello everyone,  we are new to the Real Estate Investing business.   

Note: We are getting about a 10% discount over other similar homes, and we are making the diagonal wall a wall of windows.https://imgur.com/a/x5XhJ3i

We are trying to figure out how to get started.

We understand the due on sale clause and we are willing to take the risk. 

We are able to get 4 beds and 2.5 baths in a 25x37 footprint.
