I work as a freelance carpenter, mainly for events and some TV shows, so I can control my availability more than someone with a 9 to 5.

Cable tv, WiFi, water, etc.

Tie this network into a local into your local media, TV or radio, even newspaper.

Utility service billing may also need to be changed, if any are provided to the tenant such as water/sewer, gas, electric, (internet or cable tv for many condos).With regard to "transfer the lease agreement", there is no specific "form", but a written notification needs to be properly delivered or mailed to each tenant as I described in the first paragraph of my initial response to your post.It is "Best Practice" for any and ALL agreements, and most communications to be in writing with regards to Real Estate.

Those properties in areas around lakes that were sold via late night tv are excellent areas to target.We had a buyer for 23 lots like that and it took 2 years we but got nearly all of them.We sent out letters to all 23 and only got one response the first month subsequent mailings every other month got anywhere from 2 -3  responses and sales. 

Do you leave a lock box and let people see it at their leisure? 

Many mid and high rises will have a free or discounted level of internet and cable tv from one provider.

We had snacks, wine, and before pictures scrolling on a TV in the living room.

If it's truly abandoned, you will notice most/all clothing is gone, there's no high-value items like flat-screen TV or computer, all the food is gone or old, most kitchen items are missing, etc.

I came across another BP article where the landlord on top of the regular small gifts, does a Christmas raffle with a few bigger gifts like a TV, grocery gift card for $100, slowcooker, etc.
