They should know more than the people at a big box store and be able to recommend a good one. 

Hi Kwanza,Bay Tek (650-204-1512) would be a great starting point, but I’d also recommend reaching out to Adler Builders (650-398-9030) and Mission Home Remodeling (415-855-7269) for comparable bids.In San Francisco, you’ll need a licensed General Contractor (GC) to pull the necessary permits.

For financing, I recommend you reach out to @Andrew Postell

I did it, because I had no choice, but I would not recommend it.The pictures below are all (young me) me, including the guy inside the septic system.

@Andrae S Wiggins recommend you upgrade your BP membership to Pro to access the BP Calculators to evaluate rental purchases.Play with the numbers to figure out the purchase price that gives you your target ROI.That's the number you'll need to make an offer at, NOT what the seller is asking.Yes, you will get a lot of rejects, but whoever said investing was easy?

I would recommend looking at a loan with a short prepayment penalty if looking to get cash out, that way you can refinance again if rates drop again in the near future. 

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

If you would like a few references to property management companies within the city that are local I have a few recommendations. 

Recommend you have a great understanding of the answers to these questions before thinking about a lawsuit.You'll also want to use these questions as discussion points with any new PMC you interview.If you post the address, everyone here will be able to give you more feedback about the quality of the listing and perhaps more insights.

@Marcos De la Cruz There's no hard & fast minimum - it's based on your personal return preferences...usually I recommend to my CFO clients that they make an annual somewhat higher than what they could get by investing in the stock market.
