So my question is: Is there a cost-efficient way to solve the well problem while still staying within my budget?

@Matthew Irish-Jones, I'm just looking for the most efficient way to reduce my interest rates and pull out capital. 

This was the main motivator for him; speed and efficiency was the fuel in the tank for this deal.

I’ve seen people look for mentors and I thought of a new approach; you share you real estate knowledge and I’d share my tech knowledge.Real estate is not particularly a techy field but in many aspects, software is part of our day to day, which can either enable us to operate more efficiently or slow us down and *annoy* us.So here’s my proposal - think of me as the family member who knows computers and can help you figure out how to troubleshoot your tech problems (or help with automation/other projects you might be thinking about) and exchange your time and knowledge you’ve acquired from real estate so far. 

Additionally, due to a stand-alone restaurant property's special-use case, they cannot be used efficiently for anything other than a restaurant.

You can spend money on the initial renovation and upgrades you mentioned while focusing on managing the Airbnb efficiently to start.Once you’ve made some money, you can revisit the bed/bath combo downstairs. 

As noted, everyone has their own goals.There are some efficiencies to be had with buying larger assets, yes, but there is also downside.  

Unlike a vendor or sub, there is little incentive to finish the work quickly/efficiently. 

I highly recommend a more efficient way to invest would be to partner with someone.

Then I add $25 Costco blackout thermal curtains in gray or beige which help the tenant save money.
