So I am kind of stuck with what financing options do I have that should help with this scenario.Any thoughts, connections or suggestions of what loan programs can be availed or how to go about it, would be appreciated.

I am mainly looking for single-family homes, but I am open to other options as well. 

For context, professionally Stocks and Options is my career course and comfort zone.

These options are used to tap into equity, in case that would get funds in a similar time frame as Plastiq advertises. 

Wanting to weigh up my options on either keeping the tenant until their leases up in April or considering a tenant buyout.

I, too, am exploring options in this area.

There are other options for folks with limited capital that may be more suited for the average new investor with limited capital.

I would like to be able to contact a property owner, so that I could present a potential creative financing solution (seller finance, lease options, etc.)

Yes, the bid you got is definitely high, at least compared to what I typically pay in my area. 

The rates/fees are not at all absurd and are right in line with 100% financing being a bit riskier than the typical 10-20% down on purchase.
