The big guys expect bigger volumes, and have higher costs subtracted from your commissions. many smaller ones negotiate - or only have a small fee per month to keep your license active with them.

I don't want to burn my Saturdays running around unlocking doors for prospective buyers/tenants or meeting up with contractors to pay them or sitting in front of the computer on a Sunday night to make sure I get the craigslist ads posted, and then turn my phone volume on max loud to make sure I don't miss any calls about my properties. 

This property is also in a high volume vacation rental location where most properties rent for $175 - $400 per night.

Inventory and volume are both really low, so there likely be high volatility depending if buyers or sellers emerge in the spring, personally see a small increase or aggressive appreciation if inventory stays low (2-3 months of current inventory).    

I'd highly recommend tailoring the amount of mail you send to the amount of call volume you can handle.  

Massachusetts as an example.Is there a particular sweet spot (lower end of the market vs. middle or high end) for doing high volume wholesaling?

Use a painter that does enough volume to get the best rates, it can be as high as 60% off.The have the painter use a sprayer, it gets better coverage and uses less paint.

There is so much emphasis on loss mitigation, loan mods, negative publicity and just trying to handle the sheer volume of defaults that I cannot imagine a lender/servicer making judgment chasing part of their business model.

He also said that the fee can be waived for HUD houses or when a certain amount of volume is met for the year (after 3 purchases I believe).
