What other expenses will you have to cover, utilities, landscaping/snow, water/sewer, trash?

If you have a single family, the lease can be written to make them responsible for landscaping, lawn maintenance, and snow removal.

In my market, Washington DC, almost all of our listings are on Sentrilock, an electronic key system.  

This should include a pro-forma budget showing how you plan to pay the costs (maintenance, debt service, landscaping, insurance, etc.) with the rental income.

You did not include Property Management, CapEx, Landscaping, or Mortgage Payment/Finance costs.You should always include PM cost in your evaluation (even if your are going to manage). 

I have always done some notes and then scanned in receipts and other documents (now I scan everything - so all records are electronic).If you want to get fancy with an iPad / smart phone app, Happy Co is some awesome inspection software that would could do some amazing documentation with (both safety and condition report inspections).Hope this helps.

If you change to a Roth IRA, then you lose the flexibility to convert to a Solo 401k.Make sure you have a good plan set up, but also keep in mind that the landscape will change in the next 10-15 years. 

They hold all original docs, draft the payments electronically, maintain the am schedule and do the 1098 annual interest reporting.  

I have seen pumpkin sales, Christmas tree sales, fruit stand, boiled peanuts, eyeglasses stand, carpet truck sales, landscaping storage,etc.If you put temporary things on the land to offset taxes then make sure it is not things that could environmentally contaminate the land such as a used car lot etc.

As a landscape contractor l keep copies of all my insurance paperwork in each truck I send out.
