I didn't include it when I responded above as I thought it was obvious, but after reading your post I realised that shimming the cabinets (if they do not have adjustable feet) is probably not at all obvious to someone who has not installed floors and cabinets before.Another approach we will do in older houses where floors may belly as they move away from {load bearing} walls is to put a ledger/cleat along the wall and sit/hang the back of the cabinets on this lip.

When you are out and about looking for properties, always look for those “hidden” value add potentials to be able to juice your NOI (net operating income) in addition to rents!

This is why I don't flip anything with ARV under $300k, it's just too much "squeeze for the juice". 

Your payments will be a lot lower, which will juice your cash flow even more. 

The juice isn't worth the squeeze!

Market averages - real estate, equities, or pork bellies - have no relationship to your individual investment choices.I have bought vacation rentals at the worst possible time, and at the best possible time, and managed to make good and poor buys in both. 

It is also common for floors to belly in between foundation and structural support.

Here's a very basic explanation to get your juices flowing:Assume a house costs $200,000 and rents for $1,500.

I have design plans to convert it to a 4-5 bedroom vacation rental/B&B but financing is a complex problem and I wonder if the juice is worth the squeeze. 

Very jealous of course I also benefitted from the equity growth from 2020 to present but I love that you got even more juice out of the lemon by house hacking and air b n bing the basement.
