Is this particular property within Seattle city limits?

I recently acquired a duplex in Sacramento, close to Sac City College.

Biggest question mark in my head is why hasn't this sold in 3 years.  

After spending a whole couple of days reading through various forum posts, I'm still not clear on how people who invest in 100s of investment properties, deal with their taxes.My biggest question is this: Suppose, I refinance my existing primary residence or an investment property and end up using cash-out to buy another investment property.

Too far away from the local college for walking (approximately 3 miles) and the property is located in a different city as the college which has a poor reputation. 

Here need talk to building department for address change. depend on city, some are easy some are difficult.BTW, in some Asian culture, 666 is super good lucky number.

Unless the house is worth more than 75K arv, almost no banks will refinance you out in Baltimore City.  

What town/city is the building in?

I have bought a house in the city of Philadelphia July 2016, the recording happened on that time and it has been a year so far , I was selling the property but the buyer insisted on using certain title company which made all things complicated and asked about the notices were sent by the sheriff's office to the old owner, which I never had or received or even sent to me that the Sherrif's send a notice to the old owner.Philadelphia county law said if it is a vacant property the redemption period is nothing ( this property was vacant for 10 years) if the property was occupied it is 9 months from the sale ( usually becomes a year with the recording time ), which already also elapsed, the title company who was closing the deal refused closing and asked me to do A quiet title action or lawsuit , so the old owner or his hires won't have any rights or legally won't have any rights in the property, then I was about to file that but the City officials who are responsible for the court process advised me that this case will be complicated because I will have to find that old owner who does not have any rights legally now already and service him the court case or his hires if he is dead.I am seeking your advice on the matter, and if you know any title company that is aware of the right laws and will to close for me this deal with any buyer please help me Ehab T.

The biggest issue was foreclosures and lack of comps.I feel 65k is fair based on the cash flow, but I'm just trying to figure out what my next next step will be.
