I'm looking for the cleanest & most visible way to access payment history, see amortization schedule, tax documents, etc- much like bank softwares provide. 

And you're getting tax benefits.So many of my first-time Colorado investors are afraid of looking stupid because they got a "bad deal."

(c) Do any of you have some specific market considerations I should take into account OR that I should be researching (high taxes, pertinent rent laws, etc.)?

There are some programs through local government systems where you may be able to receive a tax abatement or grant here in Michigan in an effort to help beautify a neighborhood.

Ask yourself, why would the federal government pay MORE than market rent and waste our tax dollars?

I would be beneficial to determine if they are other aspects of the property that make it a worthwhile investment (tax, appreciation etc). 

In non-community property states a husband/wife LLC is supposed to be treated as a partnership  And transferring from a revocable trust (reported on your 1031) to a partnership LLC (that files it's own tax return) is changing the tax payer. 

I have over a hundred rental units I own and operate in Utah everything from homes and condos to larger multifamily.Salt Lake County has higher property taxes and is basically built out already and Ogden even though you can find good opportunities in the long run it won't be able to compete with South Utah County or Eagle Mountain. 

Often the best risk, hassle and tax-free approach is to pay down debt.If you have a car note, credit cards, etc pay those off first. 

So, we bought the property 2 years ago, based on the valuation of the property considering income from 6 units.The sale deeds (from 2018- 3 sales) I could get from the City and the property tax statements (2023,2024) show that the property is zoned as 411 (apartments).
