Your tenants need to buck up and take care of the bugs.

Better to have your own property manager use trusted handymen to take care of the issues for long term/quality fixes. 

If there is a minor stain in need of cleaning that gets missed they can take care of that.

Do right by them and word spreads, momentum is built and eventually you are raising money from PE firms, family offices etc. if you care to grow beyond your personal network's means. 

Since they notified you of this, you should get it taken care of as your insurance may not cover a claim if there is an accident because it was a known defect.

You'll want to hire a licensed loan servicer to take care of that for you (Provident, Madison, FCI, etc).

The short answer is I look for 9% min and try to press it to 11% with those strategies along with rental increases once improvements are made and the tenants know you actually care about the property.

I still have clients but much more selective who I work with these days.Anything good NNN for dirt and tenant in strong suburban area about 2.5 million and up in price with at least 35% down.

Typically  issues are raised when the exterior is not kept up with / parking on grass / garbage in neighborhoods where everyone takes pretty good care of their homes.If you keep it clean and run a tight ship, you should be okay most of the time.

Investors typically won't care that you're representing the seller and others will prefer that you're direct to seller.Listing it on the MLS will get the most inquiries for the property.
