-Detailed inventory and inspection of owners property (this is done for LTR also, but few LTRs are fully furnished and outfitted). 

An investor who is buying the duplex next to mine wants to trade a duplex he owns in a neighborhood nearby so he can have 2 duplexes next to each other (long story no need for those details). 

Reach out for more info...I'd be happy to give more details.  

You need to properly maintain all this structure or it just gives a false sense of security.Secondly, why all cash? 

If you approached them in a way that you had a solution to the eyesore in their neighborhood they would be very receptive to talk and perhaps share contact details about the home owners son if they have them.

I'm very trainable, detail oriented, and highly motivated.

I just set up my vrbo account and still some finer details about planning the communication, cleaning service, maintenance persons, etc…

.), I'd recommend that the residential units fully cash flow the loan as my experience is that mixed use properties are tougher to finance as most lenders tend to prefer one or the other and something in the middle gets more difficult.For example, and granted I don't know anything about the area/neighborhood, I would expect this property (https://www.realtor.com/realestateandhomes-detail/111-NW-Har...) to be easier to finance than the mixed-use property you mentioned. 

One thing that could really help is creating a detailed scope of work before committing.

Provide a detailed accounting of deductions, along with the invoices, to show you’re acting in good faith.
