They are more complicated and there are more costs because the Qualified Intermediary has a lot more paperwork to prepare, has to set-up an single member LLC to acquire and hold or "park" legal title to either the relinquished or replacement property, has more liability because they are holding legal title, has to deal with a lender in many cases, etc. 

Having said that, these lender impound funds (escrow funds) are not sale proceeds from the sale of your relinquished property and should not go to the 1031 Exchange Qualified Intermediary. 

@Steve Testori - Re: 1031 -- There are a couple horror stories with 1031 exchanges where the "qualified intermediary" steals ALL your money.

You'll need to check with your CPA and 1031 intermediary, however, you may be able to reinvest your gains into RV parks and other commercial assets.

I have a back pocket single-family home in the Charlotte area I’m targeting for purchase and I’m wondering if anyone can recommend an intermediary for 1031 exchange?

I edited my post to include that I have proceeds with a qualified intermediary. 

Using this process the money is never received by the seller, because the funds are held by a "Qualified Intermediary".

These are more complicated because the Qualified Intermediary must acquire and hold or "park" legal title to the replacement property during the 180 calendar day exchange period.  

If you'd like to pursue the sale and 1031 this property, I recommend you speak with a qualified intermediary and discuss your options.

You can set up the loan with a servicing company which will act an intermediary to accept payment from you as the borrower and disperse it to the lender.
