I'm guessing appreciation and mortgage paydown combine to give you greater wealth building than this $7200/year loss. 

Or maybe you want to do a combination of the above?

@Brian Ovalle, You can combine 1031 exchanges to purchase larger properties. 

Since the start of the year, I've read a handful of BP books:- Rental Property Investing (Brandon Turner)- How to Invest in Real Estate (Brandon Turner/Josh Dorkin)- Investing in Real Estate with No (and Low) Money Down (Brandon Turner)- BRRRR (David Greene)- Multifamily Millionaire Volume 1 (Brandon Turner/Brian Murray)- Start with Strategy (Dave Meyer), currently readingI was thinking of using the equity to BRRRR small multifamily properties and combine some concepts from both the BRRRR and Multifamily Millionaire books (specifically making cash offers via HELOC to secure distressed properties, ideally vacant to set market rents).

Our combined expertise and strategic approach enabled us to negotiate favorable terms, ensuring a successful whole-tailing transaction for Partner Driven.

On any project, labor and materials are combined.

Together, we negotiated the purchase price of $136,000, leveraging our combined market knowledge and strategic approach.

Combined this leads to high cost of leveraged purchases. 

Owing to the trend towards smaller,  more efficient appliances and LED lighting  electrical loads I think are somewhat less than they may have been per SF like in the 70's through 2000's when everybody had incandescent lighting and big tube TVs and refrigerators, dishwashers,  etc. that used 2 or 3x as much power as modern ones.I've had a couple turn-of-century units rewired to remove K&T and failed 'BX" (flexible steel sheathed  2 wire cable)  and agree with other posters the pricing isn't that bad as long as you can find an electrician that has some experience with that kind of work,   and sometimes it might be helpful to open up some cable routes ahead of time for them to use so they don't have to do the exploratory work.
