If I were doing this, I would first try to find an interested lender, and then read the loan requirements and terms....and then figure out what is needed to make the lender lend....Are they requiring X down and X in cash reserves, and/or some kind of relevant experience, a (brand new SPE-LLC), etc...Maybe talk to a loan broker and get some ideas (???)

Whether the borrowing comes from equity in another property or from the purchased property is not that relevant to the math.

@John Thedford I'd just been perusing this site, and seeing as there seemed to be an abundance of people in various niches of real estate- figured I would throw it out there and weed through what was relevant, and what was not.

If I had to venture an educated guess @Michael Plaks can share some literature that is relevant and helpful.  

Rather, you just want to make sure you include all relevant expenses, depreciation, or other 'losses' associated with your property in order to get the maximum tax benefit of owning a rental.

I looked at the following:Year over Year Appreciation (not relevant to cash flow, but still important)Gross RentsLess Vacancy (HUD)Less Property Taxes (Various State and Local Governments, sanity checked with aggregated data)Less Insurance (state data - costs tend to be distributed by general geography, rather than by hyper-local factors with notable exceptions)Less Property Management (Assume 10%) Less CapEx and Maintenance (Assume $3K per year)I don't include utilities, HOAs, and other expenses, because these are often passed to the tenants. 

We are in a seller’s market.Rental Market TrendsThe charts below are only relevant to the property profile that we target.Rentals - Median $/SF by MonthYoY is up 2.6%, though rents dropped slightly in September compared to August, conforming to pre-Covid seasonal trends.Rentals - Availability by MonthThe number of homes for rent continued the downward trend.Rentals - Median Time to RentMedian time to rent maintained at ~20 days, indicating steady demand.Rentals - Months of SupplyOnly about 1 month of supply for our target rental property profile.

Not sure if it is relevant, but I have a pretty good wage and an excellent credit score.

I utilize Zillow Rental Manager but also post the property on Facebook, relevant Facebook groups and Craiglist.

Rentigo's dashboard has an almost "oversimplified" design but it makes finding the relevant information really easy.
