The data @Devin Conley posted is pretty solid from my experience (I do not know Devin nor how he sourced the data, just going by my own investing experience).  

Quote from @Giovanni Vazquez: Hello BP community, I finally bought my first duplex thanks to my phenomenal realtor Adam King in July 2024. 

Progress is slow as we plod into the final week. 

Lots of data there.

NAR Says - Existing home sales fall to lowest level in nearly 30 years and Median housing prices rose to a record high"The National Association of Realtors released data that showed existing home sales declined to the lowest level since 1995 last year, with 4.06 million homes sold on an annual basis.Meanwhile, the median home price median home price rose to a record high of $407,500 in 2024."

Here is the rental analysis data on how we came to $1,610 per unit and, when manually comp we find that's dang accurate for 4br.

Then take that data and skip trace it for numbers email etc.

Just ensure the cost data sources are very clearly documented.

They typically will have data and newsletters as well they can send you.

That being said, all of these lead-generating companies do the same thing and often use the same data to source contact information.
