What kind of trouble are you referring to exactly?

I've never managed books for any kind of investor, but I'm a quick learner and excited by the possibility of getting my feet wet in the field of investing. 

I believe that by simply adopting this kind of mindset you'll cut costs tremendously.

I'd say first, figure out what kind of investing you're into and make sure that the market you choose supports it. 

When referring to (Like kind) it focuses on the use of the property and not so much the type of real estate.

HOWEVER, on that note, just because it does not report on your credit DOES NOT mean it is non-recourse and therefore it DOES count towards your DTI calculation in most cases going forward.Off my side tangent, a true non-recourse loan is any loan that does not have any kind of personal guarantee. 

When I went into the bank they said they cannot open the account with this kind of set up.

well since banks basically dont do this kind of lending at all for 95% of folks.HML  PML or  money partners is the only way to do it .. short of using your own cash.

If you mean renting it, then it depends how expensive the second mortgage financing will be for you and if that will cover your new debt expenses; and of course by how muchFor the material depends what kind of space.

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
