Most of the content should be geared towards providing values (market trend, "hacks & tricks" of managing rentals, etc.) to your target customers, not selling about how good you are or what properties are available.

Ideally for a rental property, you want to attract quality tenants that are reliable and dependable, that’s a complete topic on its own.

On initial funding (I'd imagine I'd need this to back whatever kind of loan as downpayment): could I initially fund this C corporation, marking this seed funding as debt or equity (maybe the former is ideal in the event I want to distribute a dividend/wage back to myself from the C corporation?

Ideally, land has easy access to water, sewer, electricity, but not a hard requirement.

Obviously, a property that can create cashflow on a monthly basis would be more ideal.

I know with covid you don't want them inside, but activities that bring ten people over to mix up the drug customers will curb that business- drug dealer will go sell on the corner when there are many people coming and going.

Also, an appraiser typically will not discuss the appraisal directly with the customer.

If you need to drill out the locks to enter you have that right as long as you provide the tenants with a key - which is not ideal when they are in the process of being evicted. 

There are a lot of PMs - and landlords too, for that matter - that will gladly trade 25 bucks in rent for a stable tenant, even if it is not an ideal tenant. 

Ideally you'll still find a Realtor who can give you accurate comps for the area, but if you can't, go with your nearest guess based on current listings on the market and "Zestimates"  etc.
