All of my day-to-day expenses and the bulk of the revenue flow through the main account.

Use your revenue to pay the mortgage, property management company and expenses then pocket the rest and repeat.  

Local investors can now get additional discounts by moving up the food chain and buying as notes and, on mortgages secured by vacant properties, utilizing the preREO strategy to generate revenue during foreclosure process.

Should I play harder and get into land development?  

Here are a few things that I like about the neighborhoods in Indy compared to other states: high rent-to-home-value ratio, consistent and gradual city development, relatively low property tax and insurance cost, affordable renovation service cost.

That said it is possible that you need to evaluate your stays and decide if it is worth taking shorter stays or sticking to some longer stays to reduce your time commitment and maximize the revenue for time invested.

There are Class A industrial projects underway and the development of a large retailer.

Since you are living in the property, you probably have developed relationships with an electrician, a plumber, and a general handyman, if you haven't reach out and meet a few now, while you are in the home, so that you can easily make a call or two when it will be necessary.

It's worth taking the time to understand what you're doing so you can develop your own conviction and confidence.

I also look at future development plans in the area, as new projects can increase property values and attract more renters.
