I've seen missing support beams, various issues that builders said they would resolve / never did up until closing, etc.

Mostly this hasn’t been an issue, more often than not since I work 3rd shift I end up having to call my handyman about something between 6-7:30am prior to getting off work at 8:00am.

By law, licensed individuals are required to present all offers to purchase, regardless of who they come from or how unrealistic they might be. 

I get the feeling you aren't paying taxes on your unreported income, which is against the law. 

Luckily for us the issue was not huge, but we missed the inspection window before we found that out. 203(K)’s have higher rates than standard loans, so consider the timing of your refinance (especially in todays environment).

I think bad actors will always be around, there is a need for some consumer protection, but I think regular laws can do this.

I would speak with Jackson Law or another real estate law firm to give you advice. 

I am a licensed realtor here in Los Angeles, don't want to deal with the exodus of insurance companies and difficulty getting insurance and keeping it after a claim, tenant landlord laws being heavily in favor of tennants, exorbitant property taxes and minimal RTP among a few other factors with these being the most inspiration to take my money out of california.  

If you're considering investing in land, you need to do your homework thoroughly, understand market trends, assess the potential value of the property, and also take into account various potential risks and issues such as ownership rights, usage restrictions on the land, development costs and so forth.

It increases the liability risk, it increases wear-and-tear, the tenant is using your property to produce an income, the extra traffic could impact their community, they may be operating in violation of the law, and more.If I caught someone doing that, I send them an immediate cease-and-desist.
