Looking to invest out of state and Indianapolis is one of the area's I happened to come across.

Hey @Matt OConnor -I just looked up all of the active SFH in the Raleigh metro listed with Opendoor right now ... the median price difference between what they bought the property for and what they're trying to sell it for is only $20k - and, in just about all of the instances, they had the property relisted within a month from their original purchase.Small margins and a quick turn-around time indicates to me that they aren't doing any major rehab work - it's probably paint, carpet and cleaning.Regardless of who's selling the property, make sure you're doing the full suite of inspections and you're using inspectors you trust. 

If I'm serious about buying, my next steps would be to arrange a tour with a local contractor to get a bid on the rehab costs, get the house inspected (ideally during the initial tour so the contractor and inspector can exchange notes), and find financing. 

Does anyone have an Inspector they could recommend in Palm Beach County & Martin county?

If you get reported for living there and an inspector is sent over, you will need to get a licensed plumber to remove the code violations. 

A home inspector.

I then began to look in the Gary, Indiana area which then led to Indianapolis and surrounding. 

Hey! Can anyone refer me to a good Mortgage Broker in Indy that has worked with creative investors before and can screen my Tenant Buyers and hopefully they know a good credit repair company to put them in that will h...

do you have any go-to contractors/handymen/inspectors that I could talk to so I can get a better sense for costs, timing and, potentially, common issues to watch out for?

However, both the inspector and the pest inspector couldn't access the most of the crawl space due to its size.
