I notice this as a common mistake I see a lot of new investors/flippers make.

Some buyers (think Cary NC in the 1990s) are looking for attributes not related to economic value, like: common areas, access to public transportation, proximity to parks, etc.

A common rule of thumb is to budget around 1-2% of the property's value annually for maintenance.Management Fees: If you plan to hire a property manager or use a property management service, factor in their fees as part of your operating costs.Contingency Fund: Always include a contingency fund in your budget to account for unexpected expenses or fluctuations in operating costs.Financial Modeling Tools: Consider using financial modeling tools or spreadsheets designed for real estate investment analysis.

CO landlords can still evict for all of the common grounds for eviction: nonpayment of rent, violation of lease terms, damage to property, disturbing the peace, health and safety violations, illegal activities etc. and can also still evict if they plan to conduct repairs or renovations, property demo or conversion, move in to the unit themselves or have a family member move in, withdraw the property from the rental market, or if the tenant refuses to sign a new lease with reasonable terms. 

If you are looking for someone to teach you syndication, a common thread is to start a thought leadership platform: podcast, post on LinkedIn, post on BP, create YouTube content.I would say, if you have almost no understanding of what Cap rates are, the basics of underwriting and excel modeling, how to find brokers, etc a mentor can help accelerate your learning.
