Ideally, I’d love to integrate an AI chatbot into Zillow to streamline communication.

I have just over $200K left of owner-financing, but I'd like to obtain a cash-out mortgage/loan of $500K (ideally) to be able to pay off the previous owner and make some repairs, etc. 

Furnished Finder is a good idea, even if the fit with travel nurses hasn’t been ideal—it might be worth exploring other platforms for mid-term renters or marketing directly to local families in need of temporary housing.One thought: consider offering seasonal promotions or themed packages to draw in more guests, like holiday stays or discounts for longer weekends.

If they are legit and you don’t have any other offers then I’d have the conversation with them but I’d want a higher than normal down payment (ideally 50% or at least more than the normal 20%), a higher than normal interest rate (at least a point above the prevailing rate so like 9-10% right now, but you can structure it as interest-only payments so their monthly payment is still lower than conventional), amortized over 30 but with a balloon in 3-5 years, something like that.

I like the ideal of buying supplies instead of an upfront deposit; if the contractor skip town then at least you still have your supplies unless they stole them too.

Ideally primary, but if I can house hack a investment property then I’m open to that as well  

I want to get both tenants under triple net leases for 5 years ideally. 

Ideally you'd be there too (or a manager if you had one) as that is best practice in my opinion, but being remote you just have to outsource everything to people you trust. 

Ideally it pays itself back over the next few years and could be great!

But ideally you don't tell us, you are just going to have agents pitch their city like @Julian De la Guardia & the sort.
