I was told once over the phone my property couldn't be used as an elder care facility...

Whole Life have a very small niche in the market for instance, if you have a child with down syndrome or elderly parent that depends on your income.  

Our elders took too big a use of the 2 of 5 year rule and moved from rental to rental for 2 years at a time to save all the taxes and the government was not pleased. :-)

One was an elderly couple, the other was a single man with a decent job, just not enough to keep up with bills. 

He is a friend of a friend, of my girlfriend's family - elderly Vietnam Vet who lives next town over.

The 3/1 we rented to a late 50s couple with an elderly parent and their college-aged son who is home on breaks. 

So the elderly grand parent finds out the kids have little time for them now.Money is great, business success and all of that but you have to be present in the moment and enjoy today.

If you're targeting a community that is predominantly made up of people who might be opposed to technology (elderly, very rural areas, etc.), SEO is still better than direct mailing? 

Take the advice of our elder and wiser, your advice was misguided, you got called out on it.

At first I thought this would be an excellent choice, but then I contemplated it more and realized that many, maybe most, of the sellers I am marketing to probably aren't very familiar with texting as they are often elderly.
