The last deal I did like this, I bought a $145K home with about $10,000 out of pocket for repairs & closing costs

Having a vacancy costs money!

That being said, it can be the most satisfying and cash-flow-positive business around. 

A duplex is a great way to start because that renter will help with your monthly out of pocket costs and it's a convenient way to get into real estate investing.

Redlining IMO would only be an issue if @Jimmy O'Connor said to stay away or refuse to do business somewhere; he did not do that, he just pointed out property characteristics.

I would greatly appreciate any guidance or advice starting off with this business model.

-save $1k+ in taxes and fees yearly-can use the savings to get more insurance and a higher liability than the value of house. for flipping houses in California does anyone just put into sole proprietor own name and just use the $1k+ in savings for LLC costs into Insurance or use for savingor am I just being too risky. 

They just cost me a deal, and they are extremely unprofessional and unorganized, I'm not sure. how they are in business.

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

The repair was extensive and costly, requiring excavation (about 3x6 feet) to replace the broken section and clean up the mess.
