Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with zero or negative relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560, little to no good tradelines, lots of collections & chargeoffs, recent evictions.

His lease doesn't end for three months, so give him notice that you can't afford to charge less than $1,000 a month and suggest he move to something more affordable.

Quote from @Jacob Sherman: Log cabins are tough to finance on the exit  @Jacob Sherman Any suggestions how would someone secure financing for land acquisition and then log cabin construction?

I'd also suggest not renewing their lease before the dogs cause damages inside the house.

If you truly want professional advise to confirm what the other forum is telling you, or to assist with your own research, I would suggest paying for a consultation with a CPA rather than relying on that of a free/public forum. 

Any suggestions on what to do?

Rather than go into all the specifics I would suggest you read some underwriting books to understand how to analyze these larger deals.A few that come to mind are:- Multifamily Millionaire Vol 1&2 (Bigger Pockets) Multifamily Millionaire Book Bundle – BiggerPockets Bookstore- Hands Off Investor by Brian Burke-  Definitive Guide to Underwriting Multfamily by Robert BeardsleyThere are many others out there, but I would suggest starting with those.

If you are looking for cash on cash returns as your spreadsheet suggest, there are much better deals especially if you look for 2 or more units. 

Anyone with experience in Baltimore have any suggestions?
