So, we are not waiting and want to fast-track the process, cash out equity, and seek other opportunities.

I wanted to house hack and purchase a property that has dual streams of income.

It could be your first and last deal.I developed a few key relationships with contractors in key markets for my clients, they have a GC who organizes materials, labor, schedule, keeps everyone on track, etc. 

Having a completely separate credit card just for this purpose, and even if you don't go for a specific software yet, since you are still on your first building, actually being diligent about tracking in a spreadsheet will set you up for success.

It's really circumstantial and dependent on the transaction and more importantly, who the GP is and their track record/ past experience.

Also, certain states have very strict dual agency laws and may require the dual agency relationship in writing, which would include non representation. 

I do not know if AirBNB tracks listings by address or owner.

Especially with it being a reliable way for both the landlord and the tenant to keep track of their ledger.In terms of exterior, I agree when it comes to multis but typically we put it on the tenants for single-family residences to be responsible for up-keep.

I built a Google Forms and Sheets to track my expenditure and eventually used it balance my spending habits.

You definitely have a track record of experience.
