I think you need to focus on who specifically works in your location.

Books, podcasts, websites, and seminars provide general concepts, but real investing happens in specific cities, with specific properties, with unique rules, regulations, and market dynamics.

Quote from @Taran Sergiu: @Erik Estrada I am specifically looking for a lender who would be willing to work with a new flipper, if you guys have any suggestions of lenders who would be open to doing that? 

Specifically I'd like to model the properties I already own as it will help me learn how to check algorithmiaslly-estimated and/or wargamed values against real life actual numbers: this will help me understand that validity of the estimation algorithms.

Locate to the DMV feel free to ask me about market specific questions. 

FAQQ: Do I need to use a specific calculator?

STRs and LTRs have their own "cash flow" dynamics, which really boil down to the specific city and neighborhood you intend to invest in.STRs usually bring in a higher cash flow potential, but also come with higher operating costs, frequent guest turnovers, seasonal price adjustments, etc., etc.

CoC is fine but its a measurement based on a very specific set of data - and any of those pieces could and will change (cash invested, interest rate, mortgage, maintenance, rents, etc.).

I don't do partnerships specifically.

thinking specifically what were you seeing with demand to know it was time to add units?
