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. :)   

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). 

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.  

Should I put a for sale sign up to attract the people around the neighborhood to lock something in before it's ready? 

They have a general monthly meeting that usually attracts 100+ people from all different types of experience levels and aspects of real estate as well as some smaller sub group meetings that are more intimate and focused on specific topics.

So, the ROI on the condo is very attractive.
