I would only recommend purchasing items that fall into that vision. 

Unless you are itemizing your tax return, the interest on the primary is not tax deductible.

I think negotiations on knocking the price down on inspection items on value add will be huge especially if its a flip like you mentioned.

That's it, but a) print out a page for each property you think is comparable, b) make the list of repairs long and inclusive of everything you've done. c) Put larger items first like kitchen remodel......and don't just say 'kitchen remodel', list things like 'custom backsplash tile/Bosch appliances/recessed can lighting/pot filler/etc. d) Cite the price/value of the work done, and don't be afraid to be generous.

Your renters will destroy these items and want you to replace them. 

How much can you budget for furnishings and all kitchen items and creature comforts for the ones you want to MTR.If you have a vacant 6-unit, you have great possibilities to try all strategies.

Focus on the big-ticket items and estimate costs.Financing: Whether it's private money, hard money loans, or a traditional lender, make sure your financing is lined up.

These are just some of the additional items that will have a significant impact on carrier's rates, your premiums, and whether we start to see the insurance market soften anytime soon or not.

Are these the only items we need to document?

You're giving up some good tax benefits since you're in the tier of taking itemized deductions.
