I would also consider in finding a polite way to inform her that if for any reason, the tenant defaults on payments, that she will also be held responsible for any un-paid rents.

I have identified an ideal location, and the agent has informed me that the rent is $45 per square foot NNN, plus an additional $5 per square foot.Upon calculating the total annual cost, it appears that I would be responsible for over $80,000 per year.

How much term is left, strength of the tenant, rent escalators, rent/sq ft, etc.You also want to make sure you have a good understanding of the roof, parking lot, and mechanicals because in a traditional NNN lease, the landlord is reponsible for these items..and they can get expensive.

I just want to hold on to this rentals and rent it out and hold it hopefully forever.

It is far cheaper to initially rent in San Diego than to buy. 

Historical rent roll?

They Pd rents on the 1st of every month. 

@Justin Brown, are you saying the market is still good for rehabs, but it's difficult to rent and get cash flow?

Just started exploring what is available, prices, and rents.

Can this still work as a house hack and can still rent it 1 year after purchase?
