"I have invested with Penelope Winett, Sonoma Coast Investments & Development, LLC, several times on various properties from September 2017 through January 2021. Interest-only payments were made at an above-market interest rate for approximately 4 years while the various properties were being remodeled prior to sale. All interest payments were made in a timely manner at the beginning of each month. At the close of sale, the principals were paid in full, in addition to any remaining interest. All payments were made on time; there were no late payments during the entire time period.

I would not hesitate to do business again with Sonoma Coast Investments & Development. Ms. Winett was pleasant to work with and all investments contracts were clear and concise."

SCI&D is currently on a 1-year sabbatical or "Retirement". The owner is not sure yet and just "going with the flow" enjoying relaxing, travel, time with family & friends and life in general! At some point she might jump back in as real estate is her passion & seems to be in her blood. In the mean time, thanks for stopping by and feel free to peruse previous projects!
