Be selective when it comes to choosing the brokerage you want to be affiliated with and be upfront with them as to why you got your license so that you manage their expectations of you in the front end.For instance, they might start asking you to "Host Open Houses" Saturdays and you are thinking hold on a minute I didn't sign up for this?!!

@Dave Foster excellent info thank you.

I used to use excel but I got way too deep and nerdy with the numbers.

He did an excellent job with helping me find an investment I was looking for.

Account Closed, excellent question. 

My suggestion is to get good with excel or Google spreadsheets.

@Catherine Emert, excellent advice.

I agree that in most cases you can buy an RE with an existing ADU for less money and effort that paying someone to build one for you  However, a lot of people already own an RE that can have an ADU/JADU added, there are not a ton of RE with ADU for sale otherwise comps would be easy, some investors plan on saving money via a more active role in the ADU construction, and building your own ADU lets you select the lot, quality, design, etc.
