Box sills, windows, doors, outlets, switches, lack of house wrap under siding etc.. 

As a side note: my 1st place was also a house-hack.

It's a shame, the home is a great home to live in with potential. ( Side note, the seller only wants land value.

Take out an equity line of credit on the property that can be sides as the down payment for the primary residence.

This will likely be the smallest aspect of the company but seems like a sensible value add to the other aspects of the company, since we will have a storage unit with furniture/furnishings ready to go-Photographing properties for FSBO listings, or for clients we get for the furnishing/management side of the biz.

The home needed a lot of work including roofing, windows, siding , kitchen, baths, and mechanicals.

Most get side jobs or cash work to make ends meet but they don't put it down on app.  

On the negative side no one wishes to rent long term here!

The foundation was already approved, permitted and finaled years ago for a 3400 sf house, and its solid and I won't be building directly on the overhang edge; but rather back away from the edge a few feet to prevent any load issues all the weight will be on the longer sides of the existing footing.

On the tax side, you mentioned wanting to roll profits into new deals.
