I had amazing results using this method.

If the masonry is too ugly, then paint the brick with the correct preparation and quality paint.

Finding properties on good streets in areas close to restaurants, retail and shopping, where you'll attract quality tenants is key.

On that appraisal the 3 different methods, replacement, rents, and comps, all amazingly came out to less than 1% of each other.  

I’m wanting to house hack since it’ll be my first time and wondering if anyone has house hacked in a SFR for the first year and used the BRRRR method.

The internal debate is which method would be simplest; borrow the money as a private loan to purchase and use cash flow to pay off.

However, if you are a DIY guy, you may be ok within a few thousand dollars (granted I do not know the SOW)Just double check your comps that this property will be valued for what you think it will, and just remember that the hard part with BRRRR method is keeping good tenants!

What would be the best method, assuming that I am looking at 50,000 properties which could generate 500 gross rent, or 250 after expenses?

@Paul Sandhu what is your method in getting property at .25 cents on the dollar ?

Yes, it does cost you some time, but is probably the easiest method without a fight.
