This is a fully legal process that has been irrelevant since the 80s because rates have just dropped.

From a tax standpoint, there are additional disclosures to make when selling a business asset for less than fair market value to a related third party. 

I understand this is not a requirement, but I have never received a damaged unit from an inherited tenant or any legal issues.

Have every detail spelled out, use an escrow account and daily updates verifying all parties are executing their responsibilities.

Once that is ok'd by all parties then loan docs are generated and sent to title.Title sends the title docs to you or you can go to their office and sign. 

J Scott, one of the more respected authors/authorities on BP, provides scenarios in which wholesaling can be done legally and ethically.  

In my opinion it would be cleaner to split partnership based on monetary contribution and then remunerate each active party for their work if the active work is more on one partner than the other.

And your net worth will thank you.If you still want to go ahead, you'd be better off buying a house than an apartment because, while the value of the building itself will go to 0, you'll still have the value of the land, bearing in mind that the land might actually lose value too given the depopulation and the yen depreciation.Sorry if I'm pooping a party but make sure you understand what you're getting into (which you're already doing by asking the forum) and then make the decision that's right for you according to your objectives.

If you do this, make sure you have clear intentions and written terms each party agrees to.  

The signing parties are "stopped" from saying anything different after they sign the letter.Each Tenant Estoppel Letter states the attached copy of the tenant lease is accurate and was signed by the tenant, there are no other written or verbal agreements, the tenant has paid rent through a certain date, and there is no prepaid rent other than the current month.
