You also need a good source to acquire the properties at a discount. 

Ultimately you will have to sell your house at a discount. 

If they are good, they don't have a problem finding work so doing your project at a deep discount makes no sense for them. 

So if the property is not a value-add or steeply discounted I would not do this. 

There are accountants who say that applies to the opportunity to discount sale and/or basis shift to further lower the tax bill.  

  $500 off up front is a one time discount, the $40/month lower is the gift (to the tenant) that keeps on giving. 

Our Fourplex 100% ownership strategy has evolved over time, and based on feedback from William and others, we now charge a 20% down payment, instead of 30%.Secondly, we now pay the investor interest on the down payment, as a discount on the final price.

Guests stay full stay, guest requests discount for one less toilet.  

This math implies that the property is being purchased at a 14% discount to current market value. 

Because I had already purchased  the house building courses I got a nice  discount  on thw course I wanted.
