The pros of condo rentals is that you don't have to handle/pay for exterior maintenance or lawn care (outside of your dues). 

Some other costs you need to consider which are commonly missed from turnkey proformas - turnover/rent ready costs, "hidden" property manager costs, closing costs, and lawn care/utilities/pest control/hazard insurance (if applicable).

Would you let them park on the lawn?

If you mean it doesn't have newer homes, but has good schools, lawns are cut, houses are taken care of and it is safe; I'd have no problems buying there. 

I purposely hired addicts in recovery who were learning new skills, who have remodeled my houses, people who started their own business doing lawns and power washing, painting. 

Renting to market: $1250Tax $89.00 Insurance $136.00 Utilities $- HOA $58.00 Lawn $- Vacancy $100.00 Repair $50.00 CapEx $100.00 Property Manager $125.00 PMI $- Mortgage $588.00  Total Expense $1,146.00  Cash Flow $4.00 Annual CF $48.00 NOI $7,104.00 COC ROI0.12% Cap Rate5.07%My estimation.

So keeping the rent artificially low is not helpful financially in the long run.3.

I see a lawn in the back so I would factor in at least $50/month for the lawncare because someone is going to have to cut the grass. 

During the first year, I spent $250,000 of my money installing PEX and copper pipes in every unit, new drain pipes in the walls and under the building, new windows in never unit, remodeled 5 units, new sewer to the street, removed all the trees and plants and spent a fortune removing the lawns and installing concrete base and rocks and a lot more.So, I wasn't really enthused about owning this property because I thought I paid too much money and I did not care for the neighborhood.

I see this as a liability issue AND i'd assume it will kill the lawn beneath it.
