SFH tenants traditionally pay utilities and are responsible for landscaping.

How is the furnace, roof, water heaters.How much does landscaping/snow removal run in Missouri?

Lots of people make good money on SFR's but if you can buy ....say, 20 units of MF or more, you  have less roofs, 1 landscape, all the units are together, etc.  

Good curb appeal, landscaping is there, just needs some tlc.  

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.

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). 

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.
