@Marco Werner Be sure to analyze the total cost for building the ADU vs. the amount of rent you can get.

.+ yes, that was also my initial reservation: a house that is filled with a bunch of beds is not a very interesting space.thank you for sharing that this isn't necessarily a mistake or the wrong way to go to build it out with a focus on design/experience more than utility.

If so, I would also start building your investor database and talking with as many as possible.  

In the meantime you can start building your database of potential renters. 

I’m interested in building relationships to scale our knowledge and portfolios together.I’m so grateful for BP and everyone here! 

(He has not taken a salary from the nonprofit in 20 years- but the proceeds go to a cause he cares deeply about)  Currently, my sibling and I own 40% of the building, and the nonprofit owns 60%.

Hello BP, I'm looking to build my network and connect with other investors in the Riverside and San Bernardino County area. 

It cost me a few hundred bucks, but it was money well-spent, because it helped me understand how to design the flood mitigation system...rather than approaching it via trial and error, I was able to build a flood mitigation system that worked the first time, and the house hasn't flooded since.

How would I go about analyzing, building, financing a project to attract well healed boomers?  

start building a basic underwriting spreadsheet so you can play with the various deal inputs, test out different scenarios, and see how they perform financially.Analyzing deals is the only way one really learns to think like an investor!
