Thank you also for these ideas / suggestions. I had deliberately left out emotions and topics outside of financing. Mr. X is also very factual on the subject with Mrs. X. Mrs. X is very emotional.
The house cannot be divided into further units. The environment for a sale can be described as very good. DE central, cities and the big city reachable in a few minutes, optimal infrastructure connection. You won’t stay stuck with it for long. The environment also offers many opportunities. New residential areas for rental and purchase properties (both single-family houses and condominiums) in abundance. Especially since the starting capital for Mrs. X, if sold at the forecasted price, is also not insignificant. Many probably come out of such a situation only indebted or at break-even. The construction back then was based on good financial conditions. But not everything always goes according to plan, and then a new シ is needed.
