Even with contracting 90% of the work out – wow what an exhausting 3 weeks!

It will take some time to exhaust 100k leads, therefore it allows you to continue expanding and mail to fresh contacts for a while.

Also, make sure the dryer exhaust is properly connected.

This is the same size PVC pipe as the exhaust. 

Just in case the new duplex is wired that way too, I ordered this bath fan from Home Depot the other day:  http://www.homedepot.com/p/Delta-Breez-GreenBuilder-80-CFM-Ceiling-Exhaust-Fan-with-Light-Humidity-Sensor-and-Adjustable-Speed-Control-GBR80HL/205573460

Pretty exhaustive list actually hopefully one of these is worth a shot. 

Being constantly surrounded by your to-do list can be exhausting and depressing in itself, and those are things you need to protect yourself from with so much work to do.You mentioned things took a longish time to sell - is that just due to a slower recovery in that area from the housing downturn?  

They don’t put you through the ringer like the big banks (Goldman, Merrill,etc) with an exhausting intern or two year analyst program.

@Donnell Evans if you have good credit and a fair paying job I would avoid private money until you have exhausted institutional lending options.

Once you have an FHA loan you are not allowed to have another FHA loan unless relocating a great distance for work.Now that you have exhausted your Low Down Payment Options (Portfolio Conventional and FHA) you will need to use a Standard Conventional Loan and put 20% down to get your 3rd Duplex but by that time you might have more saved up.The sky is the limit...you could continue to buy properties and build an empire or just stop there and enjoy more free time...I have friend who quit his job and just manages his properties now.Keep in mind that this 4 step process I outlined takes time (anywhere from 1 to 10yrs depending on the person) so keep the big picture in mind but don't let it stress you out too much.
