And you are correct it was a house hack.  

I work for a local house flipper in the Greensboro area (Winston Salem).

This is for a house that sits on a small hill in the city so it would need to be someone also familiar with getting the right permits to do so in San Francisco.

Whether that's through house hacking or just another set of units I hold, I plan to purchase again this year. if there are tips on how to build a trusted network of people on here, I would welcome that.

I obviously want to get the best tax benefits and write off the expenses for the house and repairs I have done.

With value-add, I know I'm getting at least some of my capital out when I'm done and I'll end up with a house that should not need any significant cap-ex for quite a while.I'd do turnkey too if the numbers looked good enough but the reality is in the market where I have boots on the ground you're talking about close to 60k between down payment and closing costs for maybe $200/month in cash flow.

My attorney stated not only must the person who failed to pay taxes be given notice but also the squatter as well since our suit names persons who were in possession of the house. 

The reason to have comparables is if you are representing someone or perhaps purchasing a house for yourself to live in.

@Jules Aton it never ceases to amaze me what tenants will do because it's not their own house

Consider house hacking when rates and prices are a little more balanced with reality.
