Build a multifamily house as private individuals?

@nordanney and what if you do it like this: I "reserve" the property WAI(whoever) does the project development and this is paid for Buyers sign 8 purchase contracts with WAI Ongoing costs are paid by the buyers or is the whole thing (financially) not worthwhile and should one simply buy the next best available apartment?

Whoever bears the risk should also reap the profit. The TE does not want to take any risk, therefore he must also pay the costs for the "profit" and the work of the developer. Why should the developer make profit-sharing agreements, etc., if he has nothing to do with the property himself?

Your proposal is identical to the variant where you directly buy a condominium. WAI carries out the project and makes its profit. Either YOU take care of the entire project (including the sale of the apartments) or you simply buy an apartment. An in-between solution will be difficult and, from my experience, makes no sense.

@Wastl @nordanney is not the answer I hoped for, but an answer. Thank you!
