A couple of our cash flowing properties do not yet count towards income because they are not fully seasoned.

And while I agree that debt is often the cheapest form of capital, if you are looking at a project that involves some form of value-add business plan, you can always refi either when rates come down or you have increased the yield on the asset to exceed your interest rate.But like Stuart noted, for many groups, even the most seasoned syndicators, raising call cash for their deals is effectively impossible.  

There is an incredible amount of points to consider when weighing the options on something like this and honestly, I don't recommend it to very many people at all ....even seasoned tradesmen and investors.

Platforms like BiggerPockets, local REI meetups, and Facebook groups can connect you with investors seeking opportunities.Joint Venture Partnerships: Consider partnering with a seasoned developer or investor who can provide the capital while you contribute your vision and operational effort.Hard Money Loans: If you’ve identified a property, some hard money lenders may fund the purchase and development based on the future value (ARV) of the project.Crowdfunding Platforms: Sites like Fundrise, Groundfloor, and RealtyMogul cater to real estate developments and could be a great way to gather capital.Seller Financing: If the land seller is open to it, negotiate terms to finance the purchase directly with them.2.

Quote from @Jordan Kaylor: What is a “seasoning requirement”?  

Besides planning/maximizing the current tax season, I'd also plan ahead.

Use tools like AirDNA to research how often properties are booked and consider seasonality so you can take full advantage of peak times.

Most STR markets have seasonality, and there are untold issues in the future that will effect cashflow.

Based on all those factors, your best chance would be to partner with a more seasoned investor to get loans.
