The best advice is try to stay away from mutual funds that charge sales loads (commissions) and look for funds from Vanguard or Schwab that keep their expenses low. 

Down here in Texas, I use the Texas Real Estate Commission (TREC) contract.

Commissions are the usual and customary charge for services, how does an agent justify charging more for the same basic service?

Its much better then a year or two agreement off the back and they want commission of any r.e. transaction of yours in that time frame even if they haven't done squat for it.  

Commission, transfer cost, title, interest on the unpaid balance.Too many unknown factors not in your favorCharles......auctioneer

The pay structure is commission based and will require a lot of my time, effort, attention and focus.

I also brought in the brokers who put in their commission into the deal of about 300k. 

The projected numbers were: Purchase price: $27k Acquisition costs: $4kRehab: $33kHolding costs: $3kClosing costs/commissions: $8kSale price: $105kProfit: $30kWhat killed this deal was a combination of going over budget by about $10k, but more importantly, the area in which this home was located.
