You only get paid enough to continue.3) You don't need a dozen self-help books, all you need is action and self-discipline.4) YouTube University, podcasts, and the internet will only take you so far. 5) Book smarts make interesting conversation, street smarts make money.6) Find someone who is successful doing what you want to be doing and ask questions.

Yes it's a huge problem.You should fix this correctly now.Open the walls and put in proper sound reducing insulation.

Basically, the money used in this type of financing comes from "Wall Street".

@Dani Beit-Or  Yes, nationwide/Wall Street backed lenders offer HELOCs on investment properties. 

See the attached maps of his/his related entity real estate investments (courtesy of The Wall Street Journal). 

Real estate's "gross rent multiplier" is Wall Street's "sales to revenue",  "cap rate" is roughly "P/E ratio".When evaluating markets and investments I tend to start with GRM (or lazily the 1% rule), then attempt to return a cap rate based on assumptions about costs, then I work my way to multiple years of projections (assumptions about inflation, amortization, tax benefits, etc), and if I am partnering with one of my smart friends I have to pull up an IRR (internal rate of return).I also look at regional employment levels, median income to rent ratio in the zip code etc. 

To maximize the sq/ft (and save cashola) and give it a more spacey feel, I’m doing open shelving instead of upper cabinets and the countertops will extend all the way to the near wall, fully covering the front load washer and dryer units, which also have their home in the kitchen.

Water bill triples so they want to check for leaks, too many cars parked in the street. 

I.e. a property sold down the street with 1 extra bathroom and 250sf more.
