Happy New Year.I grew up in Dallas, graduated at Lake Highlands,  and my sister manages a complex in old East Dallas actually.  

Better to look at data.

Look around your town and find some relatively new apartment or condo complexes- who built them? 

Hey Dan, shoot me a DM, I'd be happy to jump on a call and shed some light on the rent data. 

First off I always question statistics when there is no possible way to gather the data for the referenced statistic.  

Quote from @Mohan Sadashivaiah: I would like to know if Data analysis in needed in Real Estate industry.

I'd suggest checking local Airbnb/VRBO data or using AirDNA to see occupancy rates and average nightly rates in the area.

They are 100% correct.The downside sometimes to forums is people have a superman complex and get the impression real estate is easy as they think everyone is doing it and just jump in without the knowledge or expertise.

With ADU's being so new and in most cases it being done for an owner who has no intention of selling, there are few data points for appraisers to currently use when determining the value of a home with a detached new construction ADU. 

Thoughts and suggestions or too complex and take the hit on capital gains tax as I sell my rentals?
