I personally made these repairs at a total cost to me for $150.

If I do buy a house I'll probably be close to house poor with no extra money and probably won't have an opportunity to invest in real estate for a while since most of my money would be tied to my house/townhome/condo.

You’ll want to look at expenses that others have mentioned such as pass through entity tax, education, networking, any start up costs, etc.  

Should i do it or no? 

However, the success of your project will depend on factors like location, renovation costs, and market timing.Many investors have found great success by focusing on high-demand neighborhoods with strong buyer interest.
