A lot of motivated sellers are going through some hardship, & nothing makes me more upset than when a seller has just told a wholesaler their situation & the wholesaler follows up by asking "Sooo how many bedrooms / bathrooms are in the house."

Bathrooms,bedrooms, and kitchen may not be big enough for most buyers as well. 

Most other capital expenditures (bathrooms, furnaces, A/C, windows, doors, etc.) are really per unit and should be a wash under either scenario. 

I have done some major renovation work include installing a wood fire burner, Air source heating, a new bathroom and general tidying.

The bathroom was recently remodeled.

Bathrooms and kitchens are the most expensive rooms in a home. 

I fixed the foundation and now I am trying to fix the plumbing issue.One bathroom in the living room is right on the spot with the foundation issue and it appears that it has not been used for long time. 

I am thinking of just replacing the countertop in the guest bathroom only2.

Where is the bathroom and kitchen in the upstairs unit?

Ran the rehab to finish the basement, add bathroom in the basement, paint entire house, add smoke alarms, hand rails, new doors, new roof, new windows, etc.
