I think your PITI estimate in both cases is low.  

I’ve been in the industry for several years, and my work has given me a solid understanding of property systems, maintenance, and what makes a home a great investment.I’m now looking to expand my own real estate journey by learning how to acquire and manage short-term and long-term rental properties.

They also hide their markups3) Biggest challenge with owners & maintenance, is owners think everything "takes only 5 minutes".

Your reserves should be part of the expense calculation: PITI, maintenance, capex, vacancy, property management, etc.

I used it to list my properties, screen tenants, manage payments, send notifications, manage maintenance.

Make use of its features like online rent collection, maintenance requests, and tenant screening.Local Resources: Consider joining the Central Indiana Real Estate Investors Association (CIREIA).

I like new construction since there isn't any deferred maintenance and the properties should be relatively maintenance free for the first couple years (although it's good to include maintenance/repairs in your pro forma and maintain reserves just in case). 

I applaud you for putting it out there but 1) maintenance/cap ex is far too low for a duplex 2) no PM. 3) vacancy at 1% will be challenging if achieving near market rent.

I hire local professionals for inspections and cleaning, but even then, I’ve run into issues where things were missed because I wasn’t physically there.3.Tools: I use software like Tenant Cloud for rent collection and maintenance tracking, but no tool can replace having someone who can physically check on properties.

The market still has relatively low entry points compared to other major cities, making it possible to find multifamily properties like duplexes and triplexes in the price range you’re targeting.
