Having leveraged a cost segregation study before, I know all to well about its tax benefits.

@Alex P.Here's a few references to start that may help you to find the answer to your question: Treasury regulation §301.7701-(3)(b)(1)IRS Private Letter Rulings 9807013, 200732012 and 201216007If you need help finding these or interpreting them, as well as knowing how reliable they are for you to use for your own taxes, consult a tax professional. 

most bay area properties appreciate at higher than 2% annually which is how much the property tax can increase annually which reduces the number of properties that would have an overpriced assessment so i would say that kind of service won't last long in business around the bay areaAfter the financial crash in 2008 resulting in property depreciation, many people appealed the property assessment and there were services back then offering to appeal but i gotta say i haven't seen those lately

Homes are still meeting 1% rule here as well, so you will see a good balance of cash-flow and appreciation.

Most that fell into the last group are no longer "real estate investors" or they chose to purchase at retail prices from the MLS.  

I've found a niche in real estate investing where I purchase a single family home with a large lot and split the parcel into two and sell the lot and either keep the home as a rental or sell it as well.

I would have the HELOC as well as mortgage to pay.

Forgive me if I'm mistaken, but it sounded quite guruish as well.

They will be well worth the money spent.

I'm relatively new to investing and need some help with my unconventional situation.First off, I'll give some background about myself.I Live in British Columbia and have been a homeowner for about 8 years. my house was appraised at the beginning of last year for $550,000 and still owe $120,000.
