Hard part is keeping on the muscle mass.

Built in the last 50 years but before 1990.Currently rented for <$7000 gross but could likely be raised to >$8000.Expenses are as follows:Taxes - $13,000/Yr or ~$1083/MoInsurance - $3100/Yr or ~$260/MoMaintenance, Repairs, Vacancy, Trash Removal - ~$1000/Mo.Now, seller wants 850k & 10% down, interest TBD.

So I’d like my property to be close because until I grow I will be doing any repairs and updating.

Out-of-pocket capital improvements and repairs anticipated during the first year12. 

(@Jonathan Greene DM us if you'd like to chat about them)Regarding turnkey in Metro Detroit, haven't seen anyone do it the right way:( We've picked up dozens of their clients that fire them due to poor tenant performance and nonstop repairs on their "turnkey" properties. 

Even in the nice locations, most top out around $2,800.Of course there is also your increased insurance, vacancy, repairs, CapEx, and the never mentioned reduced rent on the main house since having a stranger living in your backyard usually isn't appealing to most renters. 

I dealt with evictions, unexpected repairs, and the ups and downs of tenant relationships—but I also made huge strides in improving the property’s value and financial performance.

Find a renter, qualify them, move them in, collect rent, oversee repairs, re-sign leases, move them out, turn the unit, rinse and repeat.

Using these, you should be able to get most maintenance issues addressed in less than 90 days.One other thing, different tenants prioritize different repairs.

The plumber will likely have to cut open the ceiling to confirm and make repairs, so you can save a little money by learning how to do that yourself, confirm the problem, and then call the plumber for repair, then patch the ceiling yourself.As Jonathan is trying to point out, it's important to expect these things and have funds on hand to deal with them.
