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.  

You can also change the date range to display what has sold in the last 90 days, 6 months, 1 year, etc.

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.
