Typically in my experience EVERYONE is happy to help.

That data would be sales price after remodel (the true numbers some agents really don't have the experience to be comping the property), the days on market you will experience (this is great info because you want to recycle the money quickly), and resources to sell the place fast not slowly which you do not want this because this could put your holding costs extremely high and push the property to little profit or no profit. 

@Kenneth Jenkins you forgot to mention owners that expect a PMC to use contractors off Craigslist that are unlicensed, NOT insured and rarely have acceptable experience/skill - but, they quote the "best" price.These same owners will sue a PMC if using these types of contractors results in a tenant lawsuit.

From my experience: SMS has the best conversion but is the most regulated, so it depends on the rules in your market. 

A new ADU will cost over 120k to build and will not be appraised close to that from my experience and many other investors I’ve spoken with.

Many investors are willing to share their experiences, especially if you come from a place of curiosity and respect for their time.

It would be a rare new RE investor that could hope to have taken on this project without partners with experience.My point is investors in different stages of life and experience have different criteria for their RE investments.  

There's a lot of timing to consider, and honestly, this potential first cost segregation will be a learning experience for us. 

You did an excellent job summarizing your experience.

Looking forward to sharing my journey and learning from your experiences.
