Cash Reserves.... The Waiting is the hardest part

[David Palmer]

I am looking to buy my 4th investment property to live in with a 5% down payment. I am waiting on my tax return to start moving. I currently have 3 duplexes. How much of a cash reserve will I need for this move? House A PITI $2000 and rents at $2250 per month. House B PITI $811 and rents at $2000 per month. House C PITI $807 and rents at $2100 per month. Total debt owed on all 3 houses $338K. I have the money for the 5% down on a house 200K and then around 20k left over. I was just trying to figure out how much I need all together or do I need to wait longer and save.
