but your right real estate can be transacted between parties don't need a lawyer or title or escrow company or agents or lenders or anyone but the two parties.. when foreclosure rescue lease back in our state was legal I did a ton of it.. and there simply was no time to involve anyone.. when the seller decided at 10am on Wednesday they needed to take Massive action and their foreclosure was scheduled for the next morning.. 

Does anyone have experience doin this as a landlord (through a master lease)?

What is the lease for the tenants, you won't be able to kick them out if they still have a lot left on the lease, some loan types have requirements on you occupying the property within a certain time frame to get an owner occupied loan..may need to write it in the contract that they get one of the tenants cash for keys to break their lease early, etc at closing.  

Hi all - I have been considering a house hack and I am wondering how you can get a loan as the occupant if you purchase a property that has current tenants with leases.  

Typically you can't rent out a single apartment unit because of sublease clauses in your lease.

As far as your loan options, discuss that "Solely" with a Lender, as they will address all of the requirements including your self employment status and your current lease arrangement and how they affect qualifying for a loan. 

but it would probably benefit you more to have a lease and report the income. 

One is a lease agreement to rent the property the second is the agreement to purchase. 

He told the renter that they have to go after the lease ends, which is about when the violations need to be addressed.
