BRRRR cash vs. FHA/conventional

[Tyler Sokolis]

So I am in the middle of reading David Greene's BRRRR book, and I have a question about buying property with Cash vs buying with an FHA or conventional loan and then refinancing after rehabing and renting the property out.

Obviously cash gives you greater buying power (buying right is the most important part). 

And buying with an FHA loan (3.5% down) you would have to build enough equity to be able to leave 20-30% in the property without shelling out more money when you refinance.

Being a newbie investor, I am just curious if experienced BRRRR'ers find similar success when buying with cash and financing first and if anyone had any advice for the newbie who wanted to carve their path into REI through BRRRR investing.

Thanks!

FYI - located in Philadelphia, probably looking to BRRRR invest long distance, so any insight on best markets to do so would be awesome too!
