We all know that wholesale only means discounted property.

I think the issue is that it's AT fair market value and not wholesale or steeply discounted.

I do like the idea of working with them for a series of reasons (scale, financing, discounts etc)

Haven't seen any discounts for multi-family, but a PM here may be better equipped to answer that portion of your question. 

@tarquinn curry, You don't mention what your methods/sources are now, but especially due to A) (nearly) topped out market, and B) likely loss of potential buyers due to the approved law to cap rental rates, wholesalers will need to find/negotiate even deeper discounts (likely a fix-n-flip) to make it more attractive to buyers.It will take more time and money to buy lists and find off-market deals, and more time and money marketing the property to buyers. 

(I got a family discount on the rate).

So if I were able to find a property at median range, with a 20% discount, and put 20% down, at a 30year fixed mortgage, would you consider this a good strategy.

Buy one or more of the liens at a steep discount and foreclose the lien so that the property is forced to foreclosure auction. 

Notice he says “finds”There exists a pool of “buyers” who will make an offer with zero intent of closing at their offered price, they will find something to retrade a substantial discount or simply cancel. 

Investors look to purchase properties at a discount, and you will be doing that.
