We converted the space into a master suite with a full bathroom and 100 sq. ft. walk-in closet.

Read how I purchased a hoarder house at a big discount and transformed it into a high end luxury home that sold for over asking price making me $80k+ in profit in the process.

Ultimately ended up with a slip and fall suit even after the landlord took all precautions of "doing the right thing" and providing these amenities.

Our tenants are more blue-collar, some are older, some don't speak English, they aren't young tenants in the "luxury" market who are itching for this service, and just not sure how to know going in how many will actually pay online.When speaking to the software companies, one salesperson sold the idea of being able to add an additional revenue stream by charging tenants a few dollars more for the convenience of paying online -but- I have seen people recommend, in other posts here, raising rents a little and then offering a $5-$10 discount to incentive them to save money and pay online (the completely opposite strategy).Would love to hear from others, especially those at larger complexes, how difficult and challenging it was to convert a majority of tenants to pay online?  

The master suite upstairs, hosts two large walk in closets and a private porch.

Just keep doing your research and balancing out what best suits your individual situation.

During my search process I started looking for other ways to house hack, such as in-law suites or split-level homes. 

See who has the best offer that suits your needs.

Ya the real estate will likely come out ahead even at 8% once you factor in the homes appreciation, but if passivity is your goal and you don't want to manage or repair, then an index fund might better suit your needs.

@Shyam Panchal Hi Shyam, there are many well-suited investment properties under $100,000 in my local market of Springfield, Missouri.
