So many 'sophisticated' methods of investing get folks' rears in cracks I probably got carried away.  

The house was built in 1958 with original electric, 2 prong receptacles throughout the house, no A/C unit, original plumbing (copper and cast iron), original bathrooms and original kitchen.

It already has plumbing for a sink and water hooked up.

It says it has upgraded plumbing, water heaters, and electrical.  

Is the property truly habitable - as in: no creepie crawlies, leaking roof, broken plumbing, etc?

The house is habitable but needs a few updates; paint, carpet, minor plumbing, minor electrical, flooring and some patching, etc.

On our current flip we are doing all the work except electric, plumbing, and AC ourselves.- What you love & hate about it: love polishing a house that needs attention.  

My most expensive rehab to date was $60K on a $350K house that I took down to the 2x4s on the inside, rearranged the entire floor plan, rewired with permits and added upgraded panel, new windows, re-plumbed, sheet rocked, and replastered the pool as well as added all new pool equipment and blew out the inside with the latest finishes.I just put a house back together that probably should have been scraped off the lot and it only cost $35K.

I am very interested in the BRRR method for all of my future purchases, but my local bank will not do cash out refi past mortgage 4, and also require 12 month seasoning regardless.  

That's what pays off.Any serious mechanical (elect, A/C heat, plumbing etc) or unforeseen major structural that I can't do well, safely or efficiently I hire lic contractors.
