Simple furnishings bought used, a single bed, and dresser. 

The simple answer is you may be asking too much for it.

Simple enough.

While I don’t suggest that the smaller type investor purchase and utilize “exotic” vehicles like foreign asset protection trusts, family limited partnerships with outside controls, or Byzantine or convoluted maze of ownership entities, the more simple strategies of using Series LLCs, self directed retirement plans, and paying off their home mortgage to the extent of the Federal BK homestead exemptions can insure that a plaintiff attorney never even considers going after them.  

After the lease is signed, you can open the security deposit account and then provide the tenant with a formal notice that includes the account number, bank details, and interest rate.This notice can be a simple letter or email, which should meet NJ’s requirements without needing to amend the lease or have the tenant sign it again.

If it's a simple living room to bedroom conversion, it likely won't be that difficult to return to "normal" if that's ever needed but definitely a great thing to keep in mind.

When you ask a simple, direct, human questions of "hows it going", it's definatively disarming. 

As simple as that.

Is it just as simple as entering your account information in their mortgage payment portal and making sure the payment comes from your account?

Propstream is very simple to use, I would totally recommend it.
