Once the 1031 is complete it is reported by your accountant with the 8824 which reports the non-recognition of gain, transfers the basis of the old property forward, and sets up the new depreciation schedules. 

No cash out of my pocket, actually got a small check back after security deposits were transferred at closing etc..  

@Brandon Jividen I set up a clearing account at a local bank and all of the tenants can go into the bank to make a deposit or set up direct deposit (transfer) into the account. 

You either refinance and invest in additional income properties or sell and transfer your investment to a larger property using the 300K as a minimum DP or spread it among multiple properties again using only a minimum DP on each.You need to decide what category of investor you are.

There are always divorces, probates, job loses or transfers and of course foreclosures (yes I know some states have a distressed homeowner law). 

Retitle all your accounts into the trust.In addition to your living trust, you probably want to also create a pour over will that will add what you forgot to fund in your trust during probate.You would also want to look at an advance directive and a durable power of attorney effective upon disability or incapacity.Also check with a local attorney if you should transfer your homestead into the living trust or if you should use instead a lady bird deed as in some state it may create later issue with medicaid/medicare and/or homestead exemption and/or protection.

Find out how much the money will cost you (i.e. funding fee or down payment), how much will the closing costs run you (title, transfer taxes, recordings) how much holding costs will run you each month (mortgage, taxes, insurance, utilities), your rent-ready costs and what the rent is that you can expect for the unit(s) you plan to rent out.

While Tenant may use and enjoy the Premises to the fullest extent permitted in this Lease, no estate or permanent legal interest in the Property is being transferred or conveyed by Manager to Tenant herein.

Or you could form a new entity or trust, have your buyer in hand from the start and sell your shares or transfer your rights in the trust at closing, no assignments, no brokering without a license!

I found this How to Transfer a Section 8 Voucher to Another State page which basically has the info @Nathan G. said, with slightly more detail.I think it's a supply and demand thing.
