I used to watch the t.v. show, House Hunters" back in the day before every other couple they featured was queer. I wondered the same thing, "where are they getting the money"? Fairly young couples who don't even flinch at million dollar price tags or even multi millions.
#36 I had to stop watching these shows too because of this. Kinda hard to talk about it to your co-workers “say did you see that show where 2 men were buying a home....”
Some of these shows do have actors pretend to be buyers. Years ago I saw a young couple (20’s) buy a home then run into problems remodeling it in order to sell. Turned out they worked in real estate and were just pretending for the show.
There was one show that showed a Canadian couple with kids rebuilding their home. One day I see that same mother doing her own show about remodeling and she clearly could not swing a hammer. You might have seen some celebs get involved in these types of shows.
