However, the City initiated the “Buy Into Baltimore” open bid program (which we’re interested in participating) through which you can bid/buy city-owned abandoned/vacant properties for redevelopment/resale.The problem is, there are so many blighted neighborhoods in Baltimore, it’s tough to know where to start.

I tend to get questions or concerns outside of business hours, which make it tough and frustrating at times to provide immediate replies (although I do get back to the guests quickly)

You must also materially participate in your RE activities.If you materially participate in each RE activity, losses are fully deductible.

Quote from @Davin Manfredi: This is a construction material on the remodel or work done on the home, so I would say it would fall on you.

What materials are used besides the LVP itself?

Ask them to explain.2) They should provide you with the materials receipt, which you'll need for the warranty!

I want to help but also don't want him to do something that jeopardizes his income so its a tough situation.

The rules are not hard to follow and of course you'll need to plan for RMD's unless Roth but if you start a few years out this isn't tough.  

A builder’s risk policy is also worth exploring, as it can protect the property, materials, and equipment during your restoration work.
