Quick Answer
Does Dennis Fomin invest in real estate himself?
Yes. Indeed, Indeed, Indeed, Dennis owns long-term rental properties and Airbnb short-term rental properties in the Treasure Valley. Indeed, this is not a peripheral activity — real estate investment is a core part of his financial life. As a result, his perspective on Treasure Valley investment comes from running these properties through different market cycles, making the analysis decisions himself, and experiencing the management realities firsthand. When Dennis gives investment advice, it is from the position of an owner-operator who has skin in the game — not from the position of an agent who reads market reports.
Dennis Fomin — Founder, Fomin & Company | Associate Broker, GRI, RSPS | Active Treasure Valley Investor. So, here is what my investment experience has actually taught me — including the things that cost money to learn.
What Dennis Owns and Why
🏠
Long-term rental properties in the Treasure ValleyThe foundation of the portfolio. Properties in submarkets with strong tenant demand, durable rent levels, and long-term appreciation support. However, these are not purchased for monthly cash flow at 2026 rates — they are purchased for equity accumulation and appreciation. Instead, the carry cost is managed as an investment, not treated as a problem.
🏡
Airbnb short-term rental propertiesHigher management intensity, higher gross revenue potential in the right locations. Dennis manages the STR operations actively — not through a PM company. Consequently, this gives him the direct insight into what drives performance and what fails.
💡
The investment thesisIdaho’s population trajectory, employment growth, and relative affordability compared to West Coast markets provide a durable long-term investment foundation. In other words, Dennis is not trying to time the market — he is buying properties that serve the investment thesis over a 7-10 year hold and managing them to maximize that return.
What Dennis Has Learned from Owning Idaho Investment Property
1
The analysis matters more than the marketEvery investment mistake Dennis has observed — in his own portfolio and in clients’ — came from insufficient analysis before the purchase. The market does not cause investment failures. Bad analysis decisions cause investment failures that the market then reveals.
2
Reserves are not optionalAbove all, under-reserving is the most dangerous position a landlord can be in. For example, the properties Dennis holds most comfortably are the ones with adequate cash reserves. Meanwhile, the properties that cause stress are the ones that ran into a major expense event without a reserve cushion.
3
Management quality determines STR performanceThe difference between a Boise STR at 60% occupancy and one at 75% occupancy is almost entirely management — pricing strategy, photo quality, response time to guests, review management. The property matters less than the operation in STR.
4
Buy right, hold long, and do not over-engineer the exitThe exits Dennis regrets are the ones made too early — before appreciation had fully compounded. The exits that were satisfying are the ones made after a long hold where equity had grown substantially. In short, the hold period matters as much as the entry point.
5
The agent who does not invest is missing somethingIn fact, giving investment advice without a personal investment portfolio is giving advice without skin in the game. Dennis’s investment experience is what makes his investment guidance meaningful — it is tested against actual outcomes, not just modeled against projected ones.
What Dennis Does Differently as an Agent-Investor
💬
Runs the same analysis on client deals that he runs on his ownWhen a client brings a potential investment, Dennis runs the five-metric analysis he uses for his own portfolio. If the numbers do not support the investment, he says so — even when the client wants to hear something different.
📊
Models total return, not just cash flowFor example, at 2026 Treasure Valley prices and rates, optimizing purely for cash flow often leads investors to Canyon County properties that underperform on long-term wealth creation. Instead, Dennis models total return — and explains both sides.
🏗️
Has firsthand knowledge of STR operationsAfter all, managing an Airbnb is different from reading about managing an Airbnb. Similarly, Dennis’s STR investment experience gives him firsthand knowledge of what occupancy is realistic, what expenses actually look like, and what makes or breaks STR performance.
🤝
Investor referral networkLenders with DSCR and investment loan experience. CPAs who specialize in real estate investor tax strategy. Property managers with Treasure Valley LTR and STR track records. Moreover, these are not generic referrals — they are the professionals Dennis has used or evaluated directly.
