We just purchased a property through a whole seller, not closed yet, but seller has given us permission to start on rehab, but is wanting to occupy the property for 2 months.

That has nothing to do with me, you had a contractual agreement (deed of trust), that says you cannot transfer title without my permission....

A professional that can navigate and verify permissions, usages and support due diligence are critical to profitable investments. 

You just need to add an addendum stating that the landlord gives you permission to furnish and sublet the property.

They installed bidets without my permission and created plumbing issues so I had to pay for a plumber to come out several times, I've had to replace a frontdoor knob and deadbolt last month even after we rekeyed the home prior to them moving in, the garbage disposal blades were jammed so had to call a handyman, repaired a broken window which my property manager claims was broken prior to them moving in even though the repair was made 3 months after they moved in.

MTR arbitrage is a useful tool to have in your tool chest, and like all tools, it has its uses along with its positives and negatives.MTR: Medium-term rental (usually between 1-12 months)Arbitrage: renting from another landlord and *with their permission* renting out that unit to a third party, hopefully at a profit.

This will make them laugh and then you have their permission to make a boat load of money on the sale - but in our closings the Sellers don’t have any idea what our numbers are.

She did give us permission to make an offer.

Permissive ADU laws are a bright spot in CA, since they allow more ways to generate income from a property.

I would have to get permission from my company to share the lease.
