This would be subleasing and it would require the landlord's permission.

They are ultimately the same thing but I know that many lenders require seasoning.   

😎I've never required my SF buyers to get lender's insurance in my dozen or so sales, but I made sure to use a REC, not a Note and DofT. 

Rooms full of folks on the same journey have huge value.

They are monitoring what I do with the money, in the sense that they’re withholding a certain percentage of funds and requiring me to have inspections done, etc., as a way of ensuring that I put it towards a renovation and not just walk away with it.

If your estate owns more than that amount, you are required to pay a 45% tax, which possibly could cost more than paying the capital gains to being with.

I am curious what all the shady stuff these investors are doing to require such intricate setups.

Average cost where we are now is like $5000 for set up, and you may not need a full foundation depending on the manufacturer requirements and what the lender requires.

Also don't forget that you can house hack a multifamily with 5% down, but buying a multifamily as an investment property requires 25% down.Good luck!

Send the deals directly to the agents (who you can find by doing #1 above on earlier properties).They all have different buying criteria, different contingencies, different inspection practices and requirements, and different requirements for their purchases.
