According to NAR data from Nov 2021 an ADU in Denver added $170k.  

As far as renting in the local market, I am unsure where to get that data.

Indiana seems to be in a fight of residents vs data centers across the state.

I’ve seen a lot of wholesalers here shift to cold calling and targeted data lists to get more off-market deals.

Texas is also a non-disclosure state so data isn't available for anyone but Realtors.

Anything smaller than that requires more hands-on management.In a nutshell, finding deals and engaging with developers requires a data-driven approach, perseverance, and building relationships.

Focus on specific properties and areas that interest you, utilizing resources to analyze data on population growth and rental rates.

If the income-based valuation comes in stronger than the sales comps, that’s leverage for you during negotiation and a great data point for refinance conversations down the line.I would look at it as comps will drive the official appraisal because it’s a 4-unit, but the income numbers tell you whether the deal actually makes sense as an investment.

Risk that you will not enter good data, resulting in a possibly seriously wrong results2.

What are the best resources to see rental data?
