What they are selling for doesn't tell me what they're worth.Are they all the same type (size, location, etc...) or are they different? 

Your best bet would likely be cash for keys.

Can you clarify on the size/price of each as well as your anticipated revenue? 

So, when trying to split utility bills, that they agreed to in their leases, we've had Class C tenants not pay claiming other unit(s):1) Are using more of the utility then they are2) Have more people3) Are having family & friends over to wash their clothes4) Wash their car5) Etc...When we've taken nonpaying tenants to court and included nonpaid split utilities in their past due balance, some judges have thrown out the utilities.We still split utilities on multi-unit leases, but warn owners it may not be able to get tenants to pay.Best bet is to separate when possible.

The attic in question has two exits, the required size window, and a closet.

The rule in lending is you will always get a lower rate and a higher LTV loan to value on your primary home.So if you tie up money in a smaller investment and then need cash your limited by two factors the loan size and the Non-owner occupancy if it s a rental you get a lower LTV.

First, you can get into something for 0% down as everyone knows, but it can help out tremendously later on, in that once the property appreciates (which, it's San Diego so its a pretty safe bet), you'll be able to do a cash-out refi, nabbing low VA interest rates and up to 100% cash-out (though most lenders will limit this to 90%) with no PMI to help with the next purchase.  

They may be small in size, but to the buyer, these are a part of the pretty things that make people fall in love with the home.

I bet you could buy a house for $150K that would have one tenant who pays all the utilities and you could get $1600 or more rent.

I would then take that profit when available convert it into $USDT and play a 100x futures bet short or long ( most likely long) to return 4.8% profit per twenty-five dollars of movement.
