Another bonus is that it has tutorials for how to use and apply these calculations using real world examples.

Those increases are your bonus' if they occur and you should not pay the seller for what they did not do.I would still consider the rent of a unit that I was to occupy.

I currently get paid $50/house plus a bonus for leasing/lease renewals. 

Pay them enough to keep them from starving ($10 an hour) and then bonus them $7.50-$10 for every appointment they set that is kept (you actually meet with the prospect). 

Most people just don't get it and when faced with their smaller minded mentality of how to make the next quick buck, they will sell their grandmothers short if it boosted their next bonus.

I give bonuses for under budget and before time projects to my employees.

But it's owner financing, with only $20,000 down, and in a neighborhood that will appreciate as a bonus. 

I'm just wondering how much others usually pay in bonuses?

I also give him a bonus if he comes in under budget. 

You can also pay them per sign and then give them like a 10% bonus of what you make from a deal each time a buyer you got from a sign call buys a house.
