Zillow shows rental estimate of 995/month. i may be wrong but when i try to calculate things to guesstimate expenses and such i try to lean on the higher side of percentages that i hear people talking about. so i caluted at 950 for rent. then for expenses im coming up with about 835 a month only leaving 115 for cash flow every month (after refinance)  i have trouble with a couple of factors though, mainly repairs and capex obviously something needs to be held back here every month because it will happen, but everything will be brand new so risk of anything major such as roof, hvac, plumbing, electrical should be extremely low. 

Should the adjustment be based on any index or be a fixed number/percentage? 

@Damon Gainey, I think your maintenance/repair and CapEx percentages may be a bit low for a house built in 1916.

Im about to take my percentage to 30% of my check to my retirement fund from work to shift into investing in real estate.

So as I'm currently living in the property, I understand that I could potentially get a higher percentage loan (80-95%), than if I moved out and it was a pure investment property (75%).

But tbh, with a $40k loan, the fees just become a pretty hight percentage so I would think twice if that is worth it or not.

Statistically, the percentage of distressed sales is below 3% nationally.  

First, don't measure your success using percentages...they tell you nothing of value and can be very misleading to the point of lying to you. 

You therefore own more real estate and are able to deduct some costs on your taxes (either as a percentage of occupancy or by splitting expenses related to the building vs your unit).It's not for everyone because it does mean you'll have to invest some sweat equity unless you intend on servicing out the landlording.If you're looking for maximum yield per dollar invested, look toward Mercier/Pointe-aux-trembles or similar areas where the properties can be 1/2 or 1/3 of the price of a comparable building/land in the Plateau or Villeray.

Is the data of the percentage affected applicable in CA only?
