So for this last transaction, application was paperless, security and first month's rent was submitted through Cozy, and I did electronic lease signing through HelloSign.  

I use a paper/Cozy hybrid personally.I prescreen over the phone, have my own hard copy paper applications, and part of process requires them to complete a Cozy background check.If the application AND the Cozy screening check out, I rent to them and offer them the OPTION to use Cozy for payments.Some older folks aren’t as keen on the idea of electronic payment methods and would rather deliver a check the 1st of the month, but most opt to just use Cozy.

Because my database is electronic, I personalize my postcards by using merge fields.

Try Quatro Electronics, they have wireless PIR's and use a cellular modem that sends 20 second video clips directley to a central station, it's battery powered too so it's self sustaining with over a 2 year battery life (with alerts when battery gets low)

Can/should I tell my buyer's agent to show me homes electronically (i.e. via Skype or phone video cam)?

Older properties also tend to have insufficient outlets for today's electronic lifestyles, so a rewire would be your opportunity to increase the number of receptacles (and circuits) in bedrooms and living rooms .... modern code will require that things like refrigerators and microwaves in the kitchen have independent circuits and that receptacles close to water (kitchen counters and bathrooms) are GFI protected. 

It is especially powerful since most people pay electronically.

Accept rent in a way that meets the needs of the tenant, such as by check or money order, instead of insisting on rent being paid electronically or online.4.
