I tried to use an app called melio to pay some of my contractors with a credit card and it cost me more headache than planning for my rehab project.

There is no requirement to use them as mentors for doing the rehab projects as described in the horror story above, but they do their own underwriting so they will be investing themselves to assure the deal makes sense and is successful to assure they get their payments and interest. 

Generally larger commercial properties and shopping centers are easier to classify with hard and fast rules, but to the points above the residential areas really move very quickly and have way more nuance than most people care to admit.zip codes are generally way too large for my liking at least in my market to provide any kind of insights other than macro level economics but even then highways or rivers that cut through a zip code can end up with totally different trade areas.we can get pretty granular with cellphone data and with grocery center data to understand the trade areas and their true boundaries, but that kind of data pull is generally only cost effective for investors doing larger scale projects or developments, and honestly we still just end up getting on the ground and feeling it out, so I generally tell people that the money is better spent on a plane ticket and weekend trip in the area you are looking rather than any kind of "trade area" level data studies.and generally B class in 1 area means something different than another. 

However, and I don't know anything about AirBnB in Denver, but my biggest concern for this project is the ability to consistently rent the basement for $1,800. 

The judge there is "progressively" destroying rental property by allowing massive delays in evictions. 

One of my connections will fund the rehab for less and give it all to us on the upfront to finish the project at a lower cost.

Are there any strategies here to utilize bank funds for our project?

.- Large remodels or construction projects (Live in Flip) can be self-managed, worked on directly, and the value add, after 2 years, is largely tax free up to certain limits. - Many areas around the country allow for ADU Construction - house-hackers enjoy similar benefits to remodeling projects by being naturally on-site for ADU construction. 

Even though they don't need major projects or much maintenance, now that we're parents and don't live there, it's still annoying when things come up. 

Investing in single-family residence fix-and-flip projects in New York involves purchasing distressed or undervalued single-family homes, renovating them, and selling them at a profit.
