However, I do not see where you would have accounted for repairs, property management or capital expenditures/special assessments.  

While I don't have the cash flow to put down on this new property I do maintain a steady flow within the business at all times that would be able to see me through anything that isn't a massive expenditure. 

But I guess to be more accurate that does inlude a $1300 mortgage which is paid by my renters, and a payment on my heloc (that is only temporary as its still sitting as liquid in the bank since I need it to fund a rehab I am doing this month) so its closer to $3000 in just personal expenditures.

That rule of thumb says that all operating expenses plus vacancies plus capital expenditure will amount to about 50% of the gross scheduled rents.

Just wondering if people are typically holding additional money for large Capital Expenditures when purchasing a rental property in a high rise.  

At the bottom end of this there's no room to work unless you are willing to take 5k or similar - which is honestly not bad for an assignment in a dubious neighborhood with low comps and a (relatively) low time & money expenditure on your part. 

CapEx - is the Capital Expenditures.

You would adjust the number of months of cash reserves up from 6-12 months if you have an unstable job, commission based pay (i.e. it's more variable), children/spouses that depend on you, etc.Since you have a real estate portfolio, I would recommend keeping additional cash reserves for capital expenditures, vacancy and unforeseen economic events.  

Your actually negative cashflow if your not accounting for maintenance, vacancy, evictions and capitol expenditures. 

Most importantly do you have:- investment strategy- equity- financing- apartment management experience- knowledge of building maintenance, or assessing capital expenditures- knowledge about the market, returnsI have seen people go from 0 to several hundred units, but most of them are great at raising equity and also analyzing deals to find the right investment.As you take on more apartments the criteria to borrow money will change and someone will need to be the guarantor for the loan.
