The memory chips are soldered onto the main board rather than plugging them into a slot, so order it with the memory that you can afford.Backups are mission critical. 

I recommend cleaning it up well and having professional pictures taken for advertising, schedule showings on the same day or weekend in time slots, advertise through all means you can think of: Zillow, apartments.com, trulia, cozy etc.

For example:A clear or black (if you don't want anyone to see what's inside) acrylic wall-mounted suggestion box (both of which fit the dimensions you listed and even have a slot at the top for running wires out of):Link to product: Clear Suggestion BoxLink to product: Black suggestion boxOr just a plain acrylic lockable box that comes in various sizes:Link to product: Clear acrylic boxI wouldn't think it'd need to be anything too fancy or expensive.  

Assuming you guys are using conventional lending, if all three of you were on the loan, then this one property takes up a slot in each of your allotments for 10 loans.  

This will free up slots for Fannie/Freddie. 

Hey that’s the special cookie recipe you need to make, and then your golden, I have similar issues, prices now are like a slot machine or like an auction, they are all complaining about supply and demand, I wonder if my contractors hire Chinese people and these people are stuck on a boat in Cali because all of the truck drivers are on strike?????

I need to find financing for them and I don't want to use my conventional slots.

Getting around this cap will require you to refinance the homes in a portfolio loan or another option would be to offload 1 partner off of the loans through refinancing, thus freeing up some slots for that partner.

Up until about a decade ago, once you filled up the Fannie/Freddie slots, there wasn't much of a choice if you wanted to continue to expand; you had to go commercial.
