However I like the 28216 zip code area.

3 choices...Live with it, hope you never get caught...make sure it’s up to code for liability issuesGet it permitted, if zoning allows.....will involve getting permits, inspecting, modifying, tearing out portions to rebuild to codeTear it down

And let the city mow your yard two or three times and they will issue a warrant for your arrest for excessive code violations, plust the fine.

Know what they do is take 10 zip codes in your area and find the deals that way.

Depending on the zip code, $88/month for property taxes might either be realistic or not. 

So i made my decision with that in mind and purchased about 7 mins outside of summerlin in the 89018 zip code.

If you paid the property manager more than $600 for their services, and they're not a Corp then you could issue them a 1099 for their services provided to help back that you're a "business" per code 169 of IRC

While it is true in general terms, the city has over 47 zip codes.

You would have to be able to negotiate a good discount and get the property under contract in order to wholesale and unless you can show proof of funds etc. agents will not work with you.That being said  here are some ways to find motivated sellers. you can purchase lists with different motivations like absentee owners, 60-90-120 days late on mortgage, pre-foreclosure, delinquent taxes, water cutoff, code violation, evictions, probate, divorce, etc. and mail or cold call.Other methods are driving for dollars, door knocking, wholesalers, craigslist, Realtors, FSBO sites, expired listings, put out bandit signs, billboards, newspapers, other offline publications.You can use pay per click/adwords, motivated seller website with SEO, facebook, Linkedin, Youtube, and other forms of online and social media marketing.

Some of these laws are nation-wide (building codes) and some are state-specific (zoning laws).
