Also, I called and asked for a discount.

Don't jump feet first into a zip code known for high-crime, but also don't discount it. 

I believe this to be my biggest advantage because I can learn great amounts about house repairs and remodel, as well as use the business in my own projects at a discount in the future.

I try to use use their Quote Support Program and get a larger discount on big orders.

Thank you Max and Jon, I kinda caved in and offered a $200 discount for a year then the rent goes back to $1500 a month. 

So, unless the market dramatically softens in the next few days, I won't be able to wholesale the property at a discount.

We do get a trivial discount for high-impact shingles but every little bit helps. 

I have been trying to make use of the 10% monthly discount at Lead Propeller available to Bigger Pockets Pro member on the Perks section, but it doesn't seem to show up on check out. 

In the examples and statements I made here, I was intending to make the point that someone found and bought the properties at a significant discount, using a wholesaling lead generation system.

My thought though is that if there is truly a taxable gain incurred in a mod scenario after having purchased at a discount, I think the strategy to avoid that would be to use payment plans and deferrals of arrears to help the borrower bring their loans current over time.
