@Crystal Stroessner wouldn't we already be seeing much of these in the lending application data or something similar? 

Data entry person?

Research neighborhoods with growth potential, such as Journal Square in Jersey City, and use data analytics tools to assess profitability.

There is often a range of value that can be supported with market data, but when providing a single point value, they are rarely going to reconcile to either extremes of that range.

If I were you, I would pay to use Airdna data and really look at what other people are making in the different said areas.

Data, comps, and expert insights give us facts.

Albert did cover well the effort (that I claim is comparable to a brrrr with far lower return) and timeline (except sometimes the timeline exceeds 9 months, but it probably should not if the jurisdiction does its part and you have good contractors).NAR provided Nov 2021 data for many large cities of average sale of properties with an ADU versus without an ADU.  

These tools let applicants securely share their verified bank data—showing current balances, average monthly income, and recurring deposits—so you can get a clear, up-to-date view of their financial activity without relying solely on past credit.This approach can provide a fairer picture of affordability while maintaining compliance and consistency in your screening process.Here's another angle to look at this, if they have recently or are about to file bankruptcy, their debt will either be cleared or consolidated into a reasonable payback plan (Chapt 13).

I also eliminate homes sitting on over a half an acre lot since these are usually in the rural part of town or affluent properties on a golf course, lake, etc.I use IDI data primarily and have a contract with them.

Clarity on data and exit beats chasing yield every time.
