I am looking for a reliable general contractor in the Pittsburgh area for some rehab work.Any recommendations?

Craigslist is not always reliable; Many rentals advertised there are owned by mom and pop landlord types who may not have researched current market rent and so their property may be priced below market.

I am new investor in Des Moines, IA metro area looking to find good recommendations on contractors to help with my rehabbing process....I haven't been able to find a good one yet..I thought I did and the contractor is still working on my rehab when he told me it would only take a week and now it's going on 3 weeks.....time is money so for my next house I am looking for a more reliable contractor any suggestions would be really appreciated.

If you're a reliable person, I'd imagine grandma, uncle or big brother would be willing to do it.  

Have you guys had issues finding a reliable Handy man for your SFH rentals?

I would assume RPR is more reliable.

I always suggest that when hiring a real estate mentor you interview them as if you are an employer for your corporation - if they don't pass the smell test  - you should pass - find a reliable mentor or coach who has a track record of continued financial success.Charles Parrish

All brands have the same parts in them, as long as somebody competent installs them, they are all the same in terms of reliability.
