She's in the Air Force and did something like 4 or 5 deals in her first year.

Sometimes they delete the post.Sept 25 7pm - Tidewater Real Estate Investors Group - How to maximize the # of rental properties with the minimal amount of $$$.Oct 4 - Noon - Hampton Roads Landlord Assoc Lunch & Learn - We are talking about non-traditional rentals - air b&b, room rents, group homes, etc.Oct 12 7pm - Peninsula Real Estate Investors Assoc (PREIA) - They generally announce their topics right before the meeting, but it is a great group of people and they always put on a good agenda. 

I have lived in Dayton, Ohio for most of my life except for 6 years in the Air Force where I was stationed in the Netherlands.

Or you could live there for the required three years, and sublease it as a furnished rental on Air BnB for the remaining 2 years.

;) I bet the Bel-Air mansion is also in the name of a trust or LLC, and I bet it is in a different name than any other properties they may own ... rich and famous quickly learn how to become rich and anonymous, but the truly smart rich folks never seek out fame in the first place ...

I would have the ducts cleaned, furnace/AC system cleaned as much as possible, change the filter, and then run an ozone machine with fans set up to circulate the air for 48 hours.

If I could add to what John Leavelle said  ; it could cost as much as $60,000 to do a full Rehab here in the Philadelphia Area        My Friend Sean just did a Rehab in the Port Richmond Area Close to Fishtown and he it was $60,000        Sean has done many flips and I thought he went as "Budget" as you possibly can , for an example ; he paid $7,000 for a brand new HVAC  (Heat & Air Conditioning)  with new duct work , where that would have been double in the open retail market       Good luck with the project & feel free to reach out to me if you need any help or have questions SincerelyRick      

Do they use mini splits or forced air?

I have 1650 sq ft under r air and 2050 sq ft all together. 3/2 with a mother in law suite.
