I've been investing in Sacramento for years, and while cashflow has been harder to get recently, I've found that value add (adding square footage, beds, baths) is where the market has rewarded me the most.

Let's assume the 4 bedrooms are 25% of the square footage of your home.Let's say you make $80,000/year and you are in the 22% tax bracket.This will reduce the amount you have to pay on taxes over five years by: (Mortgage interest) x (tax bracket) x (the percentage of home used as rental) = $137,497 * 0.22 * 0.25 = $30,249.34 in tax savings.https://www.irs.gov/publications/p936https://www.irs.gov/help/ita/can-i-deduct-my-mortgage-related-expenses

Every state that I've been in has a few basics1. minimum sq footage for a bedroom, the room itself (usually 70 to 80 sq ft)2. closet present in bedroom3. a window in bedroom4. not in basement, and if in basement, must have exit window of a certain size.5.

Rents are driven by bedrooms and sq footage and I've rented 100's in Jacksonville to know this for a fact. 

It would be hard for me to add equity unless I would dd square footage

Typical RUBS is by number of people (water) or square footage  (heat).

You're buying by the square meter but you're renting by the bedroom so your ROI won't come from the square footage, at least not mainly.It's on a case by case basis.

To find properties, you need to first understand what type of property you are looking for and the price range.are you planning to fix and flip luxury properties or properties that are below or above the median price. what square footage are you looking for, what areas, etc.

The square footage of the house.
