I have no idea really.I guess a good way to start would be to figure out how much it would cost for the services (if I were to hire an employee) and then back in to that plus a little extra for her. 

I will gladly take the extra headaches of additional calls from my property managers for now, although once someone has enough money that they can comfortably live their lifestyle however they want, I definitely understand removing as many headaches from one's life as possible. 

Because of this I leaned more towards hiring out, but we will be living in the property for a while and are at the beginning of our RE Journey so pocketing the extra 10% Cashflow would be very helpful.

  $600 a month cashflow is $108,000 over 15 years while someone pays the extra $100,000. 

But, I guess it all depends on what you plan to do with the extra money?

In order to use them I'd have to supply the shingles and any extra plywood and (worse) drag all the old shingles (two layers) off to the dump. 

I started renting a small storage unit where I can keep any extra refrigerator (these had been difficult to find in my local big box stores lately), range and washer and dryer as needed (including if my own washer/dryer suddenly kicks the bucket).

Time to put an extra key on site Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I was thinking of adding a awning for shade and pavers on ground . since the units are so small  this extra space could also fit a table for dining besides making the laundry area shaded .will it help to increase rent ?

I think the buyer is willing to go the extra mile.
