Those sales meetings usually have at least 40-50+ agents in attendance and the vendor gets a 15-minute time slot during the meeting to speak to the room full of agents.

At that point, you just opened up 1 or more slots of Fannie Mae financing for new rentals to be bought. 

Thanks @Dan Heuschele and @Will Grabert.HVAC guy looked at my panel and I have a few empty slots so he didn't think it would be an issue.  

Only a few slots left, email me if interested and we'll work out the time & I'll share location.

We have a mail slot on the door as well so tenants can drop off rent in a sealed envelope with their address and name on it.

In a meanwhile I rent out parking slots.  

Start with the 4 plex.. live in it legally.. .refi it .. buy another FHA 4 plex live in it legally refi .Do this 4 times over 6 years and by the time he is 30 he will own 16 doors using his 4 mortgage slots  and  in the uber stable NW market and probably have some appreciation and huge tax bene's do this while your young and can make it work

Am I better off just maxing out my conventional slots before I go the alternate route?

My profit is halved, which REALLY slows down the cash flow which was slotted to go towards my next property. 

There has been considerable development around the house in recent years, primarily row/slot homes.
