I have not yet finished reading through it, i'm working on a TON of bookkeeping right now.Here is a link to the Federal Register: Final RegulationsCCH Summary:http://www.cchgroup.com/wordpress/index.php/tax-headlines/federal-tax-headlines/irs-issues-final-repair-regulations-on-deduction-and-capitalization-of-expenditures-related-to-tangible-property-t-d-9636/?

I recently read on Bigger Pockets a post on Capital expenditures that included some generic numbers. 

Not looking for any more short sales but if one falls in my lap...i would do it again if the deal had lots of $$ to compensate for the expected hassles and time expenditure.

We are super happy with the end product and knowing that it is a brand new multifamily with no capital expenditures or repairs in the new future.

I didn’t have to manage this rehab in any way, but for the first few years of ownership my concern for major capital expenditures coming up is greatly diminished.

As a little background on myself I am a tax consultant by trade (applying for my CPA license in January), and want to build my real estate portfolio that will provide solid cash-flows to supplement my earnings and accelerate my retirement.How do you estimate operating ans capital expenditures on a month-by-month basis to determine NOI?

Is a capital expenditure deduction of 30% a fair estimation of any "extra" expenses I might miss in my calculations?

Some things to keep in mind are: mortgage (unless all cash purchase), utilities, cap ex (term stands for capital expenditures meaning large ticket items such as roofs, windows, plumbing, etc.) monthly maintenance, HOA (home owners association) if necessary, legal, accounting, vacancy.

That being said, many investors mix capital expenditures with expenses for certain tax strategies, so understand before your jaw hits the floor that many T12s will be wildly inaccurate. 

Sorry - Capex is mostly hotel and builder industry speak and short for "Capital Expenditure".
