Worst case, the entirety of the $23,400 contingency allocation is subtracted from the $42,000.00 leaving a balance of $18,600.00 in the account + the $5,000 if not utilized.I would still consider this a win given the balance in the account (approximately 10% of purchase price even if full budget was allocated) pl us equity pay-down and whatever appreciation the property sees.

One of the biggest misconceptions I witness time and time again with investors is regarding their ROE (Return On Equity).For example, if you acquired one of your SFH for $100,000 and paid all cash (Mortgage Free) and we subtracted your expenses at $2,000 from gross rents of $12,000, you would have a NOI of $10,000.
