I get offers to buy my house, my neighbors house, and some house out in the suburbs belonging to someone named Daisy.

I have had this phone number for decades.

It is sometimes phishing I think, just to see if you will respond at all.

Ugh, how is my phone number even connected with their house?!

It probably isn't. More likely, she is tied to the house, you are still tied to her in some (out-dated) database

The last time one of these folks wanted to buy my house, They were calling me, my wife, and my brother (which was particularly strange since he doesn't live near me and has nothing to do with my house).

I finally responded so they'd leave my brother alone. I told them I wouldn't entertain any offer less than $1 million.

My house is not worth $1 million. Maybe if it was in absolutely perfect shape. It's a Victorian house. It used to be the pastor's rectory for a church across the street. When the church wanted to tear it down to build an addition, they moved it instead.

However, it probably needs around $200k-$300k of work to get it to perfect shape.

They can pry my ~3% fixed rate mortgage out of my cold, dead hands. I'm not selling it unless I get enough to buy the next place without a mortgage.

I was the victim of attempted title theft and like everyone I knew got texts about buying my condo.

I still get texts about it. I moved like 3 years ago.

There are a few possibilities.

1. An error in some outdated database
2. She put your number there on purpose to annoy you with spam calls
3. It's a pretext; this is her way of "reaching out" and she's hoping you'll call her to resolve the confusion

Either way, learn how the block button works, then use it.

My sister-in-law stayed with me for two months in 2007. We each moved to different states soon after that. I still get mailers at least twice a year addressed to her at my house offering to buy the time share neither of us ever owned.

Do either of you have a common last name? I get spam calls (and even more emails) all the time really meant for people with a similar name somewhere else.

I get these all the time. Do people send them their real address or something?
