I would love recommendations for an architect, I have no idea how to find one! 

Does anyone know any reasonably priced Builders they'd recommend?

Some states require landlords to accept Section 8, while others do not.There's also a process with the landlord passing an inspection, signing the contract, etc.I recommend you contact your housing office and ask them what the process involves and how long it will take. 

Does anyone have any quickbooks alternatives that work for class tracking and or can recommend an accountant (ideally in the San Diego area) that would be able to get us going in the right direction?  

I do NOT recommend any of that for newer investors. 

I would recommend taking a 'sniper approach' and marketing to owners that fit your exact criteria.

I'd definitely recommend visiting the city's planning and code department.

It's allowed me to do some of my own work like changing toilets and fixing leaking ceilings, but even if I don't want to do a job personally hopefully I'll have enough knowledge to not let a contractor over charge me, or recommend something I don't need.You'll also meet local contractors, and hopefully investors.They may offer an employee discount too.

I don't think you need to know how to underwrite your own deals, but knowing what commercial underwriting looks like and the metrics mean would be a good place I would recommend starting. 

Do you have any recommendations on lenders or someone investing in real estate in the area?
