Don't forget the gals... there's some heavy hitting REI ladies on this forum.

The house is otherwise a very attractive house.

You can get a lot of year long leases if you have the right perks to attract people in the summer, and at worst case you do 9 month leases(Aug-May).

If you are going to focus on the lower quality homes then your end investor will attract lower quality renters and will have more problems.

There are threads here about how to manage these situations, but we'd be getting off topic setting up notices prior to doing something, the OP appears to already attracted attention. :)   

I had someone there and the heat fixed within one hour. 2 weeks ago, A tenant called(single lady) at 1am in the morning, a pipe had busted going into the water heater, I led her through calmly over the phone, shutting off the water.

As a realtor, with a friend/partner as my Broker, I have the ability to list properties with a more attractive split to the selling agent - a 4-2 or even 5-1 split (for those that bring a full price in X days). 

Ladies and gentlemen,I was very excited to learn that my business partner and I are ready to make a move on a MFU 3-4 plex in 2015.  

Market has been proved that private showing session of this house attracted at least 60+ different buyers, very hot market, so selling should be easy.8.

They work with a lot of investor and definitely offer more attractive terms than the typical hard money lender.
