That's a good process! My personal pain-point in this is paying way too much rent for way too little. (However, that's just the supply/demand mechanisms doing its work). But also, the landlord aren't delivering what it promised before I moved in...
It might be interesting to look into creating a service for form-letters for various real-estate complaints. I know that previously, I've had to deal with landlords who were withholding my security deposit, or refusing to make repairs, and a way to quickly generate official, legally-correct letters for requesting what I am legally entitled to could be useful.
