I have owned rentals for over 10 years and have residential construction in my background, so I am feeling good about this new venture.  

Sounds like $15k might be a generally safe bet on houses that look "pretty good"... and obviously upwards from there if adding an additional room.Property management fee: Yes, 10% was my starting rate there, but I have 4 properties in the area currently and my management company has a portfolio rate of 8% once you reach 3+ properties through them which is a nice little bonus.I should have caught the property tax difference!

Currently under construction is a waterfront community right on the Hillsborough River, including Amateur Works (dining and bar scene), apartment complexes, event halls, and commercial business offices, ect.http://www.tampabay.com/news/business/realestate/t...Jeff Vinik and Bill Gates have also began a plan to invest 3 billion dollars into rejunivating the city, which in result is increasing the values of all the suburbs surrounding the city.

I use a combination of HELOC/construction loans to roll everything until sales and get extensions to the loans if I'm holding them longer than a year.  

I would say your best bet is to attend the next Hoa meeting, ask them how they tried to contact you, and then ask for a “reasonable” $50-$100/month fine.

I dont know all the ins and outs of airport construction, but even if I did, I think I would still buy an existing one.

Are you getting 40% of the equity in the value after the construction?

I am trying to get a sense of the cost of rehabbing homes/construction in Philadelphia for a light rehab, mid rehab, to full gut renovation/shell on a price per square foot basis.

The lowest amount I've seen is 20%, your best bet being an Agency loan.
