I still have some reserves after funding the entire loan, like you said I just want to have cash on hand, especially if the housing market dips.

I have a long list of people who want to reserve a vacation on out lake property.

Year One (Save >15K)Get back home around August; go back to work two weeks later.Sell the truck and trailer.Start prepping the house for renters.Get a job at Wright-Patterson AFB.Sell all unnecessary furniture and miscellaneous.Vet and sign renters.Move to Dayton, store all the necessary furniture, and rent out a motel at monthly rates.

We own all our properties in one ocean front community on Hutchinson Island, Florida and the POA sent an email highly encouraging owners who rent to vacation renters cancel all future reservations going out 90 days. 

In the House Hacking Strategy book by Craig Curelop, I know the recommendation was to have  at least $10K reserve  per househack but not sure about the cashflow.Also, what are some great ideas for a good house hack deal in Ottawa for those in that area.

Hopefully most owners have cash reserves!

I am not looking for advice about having more reserves, or making better investments, just looking for great ideas on how to go about this rather delicate yet sensitive process of negotiating rent payments, while people are not getting paid. 

For example, if I were designing such a model and had all the data available to me, I would include distance to a highway as a feature, school quality, or even creative variables like the count of liquor stores in close proximity, income of zip code, average age of neighbors (to know whether they're adults and poor or maybe just students)...

I like the Federal Reserve Economic Data website, but it doesn't have everything.

Your big box stores will have some in stock, you just have to cut them to size, cut a sink hole in them, and install.
