Convert basement into a studio. Need some advice

[Derrick Wilson]

Hello BP Nation

I live in Yonkers NY I want to convert or finish my basement into a studio apt. There's two Windows and a separate private entrance. I would need to add a bathroom with stand up shower and a little range.Once converted it can bring in about $950 my mortgage only $1330. I would like any advice or tips on how to go about this from any one who did this before. I know to hire a general contractor and get some quotes but its so much info on here I had to start here first. Thanks for your input.
