After some back and forth with the seller's agent, the seller how signed and returned the LOI to me.We're now working on submitting the PSA & scheduling an inspection, but my team will be out of the country for 10 days.My question is: I am running any risk of seeing the seller move on and find another buyer because we're "slow"?

In addition the real estate investment journey in flipping/whole tailing (no deals to date, still on the hunting mission, we’ll get there), my wife and I are considering moving out of our home (70% Ltv, been our homestead for >3yrs), getting rid of PMI to lower mortgage payment then renting it out as a positive cash flowing long term investment and buying/moving into a new home then rinse repeat in another 2 years.

Turn key or are you willing to hunt the deal down and do some rehab?

I've searched through my entire pre-licensing course and I couldn't find anything.In Florida, is it illegal for a licensed real estate agent to receive a referral fee from an unlicensed buyer or seller for bringing them together?

the gurus sell the idea of wholesaling as easy and no money down but that couldn't be more wrong. there is no guarantee return on the money invested in marketing . a wholesaler needs to do a lot, a lot of research to the local market where they are trying to find deals. you need to not only find the deal but prove that it is one to a potential buyer/investor. now Im not trying to discourage you, there are plenty of ways of getting started without MUCH money down .you can get a few cards made at a copy/print shop. you can talk to people and let them know what your trying to do. you can build a social media platform which is free. remember as a wholesaler your simply trying to find the deal then sell it at a commission. a friend of mine that is an agent uses their title company  to find information on houses in my neighborhood,  become friends with agents!.

I suppose they would mostly be buyer leads.On top of that if I wanted to get in to one of my preferred zip codes it would cost a ton of money.

If you need to sell and its a buyer's market. 

There are also some states that require a judicial foreclosure if you finance the sale yourself and your buyer defaults, making the deal much more expensive and time consuming.

Do buyer's real estate agents try to get you the lowest price possible, or do they usually not bother to negotiate?

Spend that time learning instead and waiting for the better buyers.I get contacted daily by buyers in the commercial space.
