My first questions to get answered are always:-  Do they have an existing mortgage or do they own the home free and clear (if a mortgage is present, do they need to pay it off for the deal to work)- Do they need the cash or do they want a prolonged income streamAnswers to those questions can help understand some of the key seller motivations.A typical seller financing structure would have a down-payment that would range from $10-$20K up to 10%-20%.Interest rates typically range 1-4pts over residential real estate mortgage interest ratesIf the seller wants long term cash-flow, the term can be 10yr-30yr.   

The long-term tenant probably has a higher chance of staying, but it would be much easier for me to have them move, vs. having to buy-out the current lease of the June 2019 tenant (or do cash-for-keys).

Short of this the seller likely had an out for not being able to “deliver clear title”.I always, always run a prelim title check before getting into contract. 

I used to use padlocks, but it‘s expensive up front and also re-keying when keys get lost, and I had to meet with tenants to provide the key.

They are planning to give us the keys at the move out inspection even though the lease explicitly states that keys must Be returned within 24 hours of lease end.

The key is to find a local commercial lender who understands your business and sees the value.

I am currently reading Yardi reports, Marcus and Millerchap reports, ABI, CBRE etc, but am interested to hear about other reports you may find key to your inveating like these monthy or quarterly reports, but also what kinds of material you are reading daily or weekly to keep up with your markets and the multifamily industry.Please share your thoughts and get some conversation going!

He also hasn’t given me the keys to his side of the property.My question is, should I wait the 3 months and see what he does next and curbside his trash?

@Ben Davis for me timely communication is the key.

This is key to growing a real estate portfolio at a reasonable fast pace.
