Times 2 years, and you'll be $3k short of your projected expenses.Now add into the mix the increase in costs from what you are using now to estimate your future CAPEX off of, and you won't have enough money...even if all goes well.Saving for CAPEX through your cash flow is a losing option.Let's just see what happens if you do have added costs, and vacancies per year:assume 1 month vacant and one month worth of added costs per year, and you would end up saving only around $4500 per year.That would put you $6k short of your 2 year estimate, and (assuming you will only have the 3 years after that) $1500 short at the 5 year mark.The HELOC is there waiting for you when you need it.

I was wondering how often do you increase rent, and what % do you usually increase it by.

Since Vietnamese is a single-vowel language, each word can combine with another to make a completely different meaning sentence, that's why whenever I tried google to translate between English and Vietnamese, it always gives me funny result. 

gradually increasing rents?

Not to mention the improvements will result in a 200-250 a month increase in rent, reduced water use and electricity.

I noticed that the lender increased my mortgage insurance (MI) premium to almost double the original amount. 

While it may be too late to increase the rent for May, you should not have to wait a year. 

Even if you increase that 2nd unit from $750 to $1000, doesn't seem to cash flow that great after maintenance/vacancy (i used 15% in my modeling).my 2 cents. good luck! 

So my expectation is that went a loan comes due, I'll have the funds to pay it off in full, and if I do not or would rather not - I shouldn't have any problems refinancing with the same or alternate lender.Plus, if the property has appriciation during those 10 years or is a 5-Unit (or more) multi-family that has been maintained and managed well (increasing rents), it should be worth far more than owe'd, further making it easy to refi.

Renovations are being done and rents expected to increase to $1500-1700.
