Is brokering, or a listing agreement.Personally, I don't think either are technically wholesaling and would not call either one wholesaling ...

Read books on investing in real estate, listen to the podcasts, attend webinars and stay active on the forums while connecting with other investors in your area and pick a niche.

You technically buy the property with the buyers money, hold it for a good 5 mins and then pay the seller. 

Technically you will not "share" a wall in spite of how it looks, technically there are typically two complete walls... they just touch and good luck separating them after 15 years.

You might consider Niche or Specialized Housing like student housing.

So technically no the mortgage company sends it to a management company and they assign it in most cases.

The voucher is technically a HUD voucher that was issued by a local "public housing agency" (PHA).  

During a foreclosure situation there is a redemption period for the person being foreclosed on, perhaps your friend is being hired during this period when the property is technically in limbo.

What I want to protect myself from is setting the start date to 10/1 but having them move in on 9/23 and having 7 days where they are basically living in my property under the terms of a contract that technically don't start until 10/1. 

I can certainly see the attraction of putting less down and using the first-time homebuyer option, especially as you only get to use it once (though I think you might be able to use it once every 5 years if you haven't owned for several years - there are some technicalities but basically the easy answer is that it's a one time use).If you put less down now, that leaves you more down payment to use on a second property (either now or in the future).But I would caution you to make sure the #s work OK on this first property, if you go with the low-down, high-leverage option.
