They do try to sell you on turn key properties but the information he dishes out is invaluable.

Consider installing Fiberglass Reinforced Panels (FRP) without any soap dishes.

An acquaintance needed to relocate for work out of state so abruptly that she didn't want to get a storage unit for all the furniture, dishes, etc.

I would spend more money on the fridge vs the dish washer.

I would recommend cleaning up because his new landlord may be coming in, but if they choose to leave clothes all over and dirty dishes, that's up to them.

Best advice that I've learned so far is identify your market, the type of property you'd like, figure out how much you could dish out per month to pay for a mortgage (safely), get involved with an agent and lender, and start your journey.

Dish washer/ washing machine/ big appliances create heat and eat electricity even more if they are old. 

Are you prepared to deal with a sink full of dirty dishes on a daily basis, or your tenants having friends over late into the night?  

Kitchens in San Diego have around $50/month cap expense (a lot to go wrong in a kitchen (refrigerator, stove/oven, garbage disposal, dish washer, plumbing, etc.) and typically need full rehab at 15 to 20 years). 

I have been fortunate to visit many Asian countries and befriend a great many filipino, japanese, korean, thai, and vietnamese during my stay in Hawaii.
