Current owner hasn't kept the best record upkeep, as five leases expired years ago and are on a month-to-month, with the other three leases expiring this year.

I use QBO, so I just log on my cell phone, because I can snap a picture of the physical receipt or invoice to be saved with the record online, and then I can throw it away.Acquisitions: I am not actively trying to grow my portfolio, but I do have alerts setup through the MLS that give me emails everyday. 

They trusted me and saw that I had a track record of rehabbing lots of houses for years(not my first deal or second deal or third deal).

As you build a track record, more and more people will want to invest.

When looking at their records, there is also a special assessment for almost 50k.

Besides going door to door, I would search city court records online for divorces, judgements, bankruptcies, evictions.

Example: evictions records, newspapers (the worst place to advertise is often the mom n pop landlords go to), local (city) complaints department etc.

shows as single family on the tax records.  

I even reviewed with him that the tax records say that the building is a SFH but he assured me that the town does not restrict use of lots to SFH/Multi/Commercial/Ect.The CEO is willing to write a letter explaining that to the appraiser that the transition from a SFH to a Multi-family was completed 20 years ago and there have been multiple town assessments sense that time.

@Toni Conway You should have one tab that records all the transactions and another tab that summarizes the first tab.
