Is there a digital door lock whose code you can change remotely, without a monthly fee? 

. :-)There is such a low bar to entry into the field, and frankly it is an incredibly complex job (once again, to do it right) Heck, I even had a license (in Cali) back in the day.

This, however, changes not only from county to county but also by neighborhood, zip code, school district, etc.Another change we are witnessing in real-time is increased seller’s concessions, which can go towards financing closing costs or buying down the interest rate.

Also check for back property taxes, code violations (which may not be wiped out by the auction), etc

We also had some exposed wires under the house that required some minor electric upgrades to bring to code.

@Femi AjayiRecommend you do your own research on this and visit the places you consider investingThere are 41,704 zip codes across country and no idea how many on east coastRegarding cash flow and appreciation - they do not go hand in hand.

See the below screenshot.If the zoning allows a 3-family, you would need to meet all the rules and regulations in the Building Code as well as the Zoning Ordinances.

Guess what statistically a half bath adds in value in that zip code?  

These are professionals with additional training and a stricter code of ethics.

I started my career in restaurants backwards, I opened a bar and restaurant at 27 with no experience and ended up losing roughly 350k after about a year being open.
