Specially in South Carolina taxes are a killer.

I specialize in off-market distressed single family homes and smaller multifamily (duplexes, triplexes).

I am an Indianapolis realtor, as well as an investor myself, and I specialize in helping investors in the area!

I specialize in STR's along the coast and have had a lot of success with MTR's for medical professionals as well.

HOWEVER I just met someone from PadSplit, and partnering with a company that specializes in that could be a really great approach.

I've found that cost segregation companies don't always do a great job and will miss  things even though it is something they specialize in. 

Beware of FS and the teams they work with specially in Detroit area.

Then depending on what's allowed you can speak with a broker who specializes in that type of property (agriculture, industrial, low density residential, etc.) and see what they think the highest and best use could be. 

I specialize in both and would be happy to help you crunch the numbers!

Any decent Contractor can generally buy products for much less than you anyway, and even if you find a special deal on, let's say, Doors and Windows...who is going to take charge of delivery, unloading, storage, security, warranty and all that?
