At the end of the day, you are taking a risk and you have to make the best decisions you can with the information you have available along with your intuition and of course at all times must obey all fair housing, anti discriminatory laws or practices.

It is common practice for them to pay the 11.5% for Walton and Okaloosa counties and 12.5% for Bay County, and the renters pay the cleaning fees. 

In practically all these cases, the first thing I did was serve them with a 30-day notice to quit to terminate the old tenancy.

This means that the common wholesaler strategy of assigning a contract will not fly, and neither will a simultaneous double-close (how would you get a buyer without marketing.)I am sure people will tell you they have done it, and gotten away with it.  

If you are saying that it is $150K up front, and two more payments of $150K than that is called a net commission deal in that he is getting the overage of what you wanted on a net basis and what the bank has agreed to pay and is outside normal practice but not unknown.

Example #1:1 - Bring in a cash partner at <fill in the cost to buy in and % of returns they are buying>2 - Put a timetable on their involvement, with a payoff of their original capital + returns.3 - Use the funds to pay off the remaining balance in the original property's debtExample #2:1 - Bring in a cash partner that pays off the existing debt completely, and give them a guaranteed return based on the time it will take you to do the conversion and sales.2 - Use the funds to pay off the debt.3 - You now have 100% equity, and you're freed up to get the needed funding for the conversion...and all of the original funds back for use moving forward with your next deal...simultaneously. 

Practice doing calculations on potential properties as they come on the market to enhance not only your understanding of REI in your area but also to develop an idea of what a great deal looks like.

Please share experience on this if you have some, I'd love to know some best practices.
