Another fun fact is you will forfeit your right to sell the properties at will; only the Sponsor can make that decision and most properties are held 3 to 10 years. 

My leases stipulate that the tenant forfeits last month's rent and deposit if they vacate early.

If I find something in their background, i will return the money to them and move on.if they call me up and say they've found a new place 2 weeks later, they forfeit the $200.00 and it's mine to use to re-advertise the space ect.

I also have this sentence:  In addition to forfeiture of earnest money to Seller or return of earnest money to Buyer, Buyer and Seller shall both have the option of enforcing specific performance of this contract or any other remedy allowed by law or equity.Does this mean that I can still be forced to buy or pay other damages after forfeiting my earnest money if the deal falls through?

In some situations you forfeit your earnest money when/if the deal does not close.

The reality is that if you refinance and close within the first 4 to 6 months after closing on the purchase, the lender who helped you with the purchase will forfeit 100% of the commission/revenue the company earned on the loan.

If they flake on moving in, they forfeit the deposit, but if for some reason we aren't able to rent to them, we would return the deposit.  

About 30% forfeit less than $100 of their deposit.

Laws § 600.5701; A land contract in default can be accelerated and be foreclosed without first giving the vendee notice and an opportunity to pay when, in the same circumstances, the contract could not have been forfeited without prior notice.

Additionally, the seller must provide a written notice of default that advises the purchaser of:a) the nature of the default, including the amount if the default is a failure to pay;b) the date by which the purchaser must cure the default or the option will be forfeit; andc) the name and address of the seller or the attorney for the seller.The notice of default must be served by hand, sheriff, or certified mail or equivalent.What if the purchaser does not remedy the default?
