If there are barriers that limit similar supply and you figure out how to get the housing units online, even better.

@Shaheen Ahmed you can find all the info you need online if you know where to look - except that the City of Detroit Assessor's Office is consistently undervaluing properties to keep property taxes attractive for investors - to keep improving the city:)Here's some copy & paste infor for Michigan Property Taxes that you might be able to use as a template for other areas - or you could start investing in Detroit:)----------------------------------------------------------------------------------------------------Michigan has some of the most complicated property taxes in the USA.

A lot of that is referral based or people find my site online, organically. 

Quickbooks online could work for what you need.  

You can also check online resources like BiggerPockets or Roofstock, which offer general CapEx guidelines based on property type and age.These methods should help you perform a solid preliminary analysis.

I’ve found success by networking at local meetups, connecting with real estate agents, and exploring online platforms to discover these opportunities.

Take a close look at what other similar units look like on Zillow or other online listing sites and try and mimic them or exceed them.

IMO killeen is a solid investment. just have to watch which areas you are getting into. there are some pretty rough areas near fort hood but killeen is great because it is close enough to austin and people commute from there to austin as well. with fort cavazos near by and the new samsung plant coming online in taylor, it is a solid choice with steady demand for MF.

You can create your own, or there are house flipping spreadsheet templates available online
