My clients can "force appreciate" the value of the property by doing a quality rehab for a lower than market cost because they are very good at spotting "diamonds in the rough".

Then you can read a more in-depth book like The Book On Rental Property Investing by Brandon Turner or The Unofficial Guide to Real Estate Investing by Spencer Strauss.2.

I've been following the build-to-rent method for some time and even lived in one for 2 years.

My name is Renata Johnson and I'm returning to BiggerPockets to learn all about BRRRR method, along with other forms of Real Estate.

Quote from @Paul Lucenti: Creative methods tend to increase risk.

I have been paid off by Cogo loans so I know it happens. 

Philly, like a lot of major US cities, is very block by block.

I have improved fair rental value and value by increasing the kitchen size; adding an island tearing down walls between the kitchen and dining area and living area, etc.It all depends on the particular property. 

Personally if you are looking to grow in real estate going the traditional method/way of getting good properties under agreement with traditional financing will get you to where you want to go faster than trying to find all the needles in a haystack.

Kudos for taking action and adjusting course when needed!
