A good real estate accountant can save them thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend that they find a tax accountant who specializes in real estate taxation, business taxation, financial planning and tax planning.I would also recommend that they look for a accountant willing to work with them throughout the year, who can help them strategize and who is responsive when they want to know the consequences of the financial decisions they are making throughout the year.Good luck.

Non-passive to achieve this level of return.Add the addition of the ADU makes the main unit rent controlled if over 15 years old.the work to add an ADU likely exceeds the effort of a brrrr that can achieve infinite return  Experienced investors are adding multiple ADUs by leveraging items like bonus density, committing units to affordable housing, etc.  

I already have land holdings near Everett that will certify out at 304 salable density bonus credits.To play this game, I get certified and then "clip off" the transferable development rights for sale to urban developers in the county, who can cash them in for an increase in dwelling unit density from an original 22 units/acre to 58 units, and building heights from 45' to 75'.

@Michael ReilmanI installed the Aquasource Henshaw from Lowes in all 20 units I recently rehabbed and they've been great so far, and as an added bonus they're ADA height which is awesome for bad knees!

Finally found this one and took advantage of the low interest rates by winning the bidding war with an offer slightly above asking price.

It could be a massive failure, but it could also be a small - moderate, LTR win.  

@Mike Levene First note, I agree with others saying cash flow is a bonus, though it depends on what stage of investing you're in.

The big assignment fee is just a bonus!

Nobody wins in that situation. 

Depending on how you use the property, you may benefit from a cost segregation study and bonus depreciation once the property is in service.
