As a goodwill gesture you can order an exterminator package to calm them down. 

I'm putting new homes 'to-be-built' on land in my area as a Realtor, so I'm listing the land and marketing the house as a package.

We always have a notice of assignment as part of the closing package that satisfies the regs whether or not there has been an addendum in the contract. 

If you are accredited then you'll be able to receive marketing packages from sponsors and view them online through website like Realtyshares.

Zillow will not really work for selling, for packages you might try talking to net worth realty or own America and see what options they have.

Create a package for it and blast it around to investors on BP.See if someone is interested in buying it off you and you can do a FSBO

Rumor has it that they are doing packaging for amzn.

If I had to do it all over again I would package together similar properties that I would likely want to sell all together. 

Then you can confirm they are not on the FHA approved list here: https://entp.hud.gov/idapp/html/condlook.cfmThen if you find a good deal you can look into the HOA resale package and find out why it is not on the approved list and then see if it is a good fit to become FHA approved once they loosen FHA guidelines on these restrictions.

Also started doing Amazon Flex (delivering packages) but that's too recent to count.
