I have JV'd with this flipper on previous deals and we split the profits based on a percentage of how much each of us had in the deal.

Parking is almost always the start of any problems you might have with the neighbors, HOA, or city.It can be very profitable. 

But still simply exchanging into a property with identical cash flow and all would net you more each month.The key of course is that you do it without triggering a recognition of gain.

and soil conditions can make owning rentals there NOT profitable for out of state investors. although with your down stroke you will most likely do fine..

One last point: It is important to ask if they have any limitation on the amount of profit spread between the A-B and B-C transaction.

Equity is not really investing or increasing cash flow it is simply a expensive way to buy cash flow and park cash you have no other use for.

It will be more profitable in the long run.Second, it sounds like you have focused on a geographic area in Florida.

Do you know if they simply wrote a letter with the property/account info with their offer amount?

Most beginners after their first year worry about how to deduct all their losses instead of how to reduce taxes on their (non-existent) profits. 

Those who really earn their commission do so through market knowledge, problem solving abilities, and negotiation skills - they can save a deal when things go south.As an investor, commissions are simply a cost of doing business.
