Hi Joseph,
I am a realtor in the Indianapolis area. I have about 20 investors that I am actively working with.
I believe Indianapolis is a great area for all of the reasons you listed. We have a very low unemployment rate and it has stayed consistently low for several years. Our area has attracted several big name tech companies, but is a good solid blue collar worker area with plenty of manufacturing jobs and distributions centers. The rent to purchase rate is very close to 1%. In the past year, I have been able to find my investors $60K-$90K houses that rent for $750-$950, $100K-$130K houses that rent for $950-$1250, and a few higher. It is a friendly landlord state - state property taxes are capped at 2%. And yes, we have several big name companies, SalesForce, Eli Lilly pharmecuticals, Amazon, and Rolls-Royce to name a few.
Flood insurance varies on the size of the house, but for the type that would be good rentals I seem to find range for $80-$100 a month. Some of my investors have me avoid flood areas all together, some just figure the monthly cost into their figures.
I would love to talk with you further and get a feel for your exact parameters. I have a really good lender and property manager that I highly recommend, but also network with other property managers, contractors and wholesalers in the area that have high levels of integrity.
Let me know if I can get you any further information.
