就是说:cash reserve is pure cash or other liquid asset, do NOT count rent or other potential business income. 理解对吗?
这样的话,贷款越多,monthly obligation 越大,cash reserve will have to be bigger!
For example, if one has 11 properties with monthly mortgage payment total of $9k. Then the cash reserve will have to be $108k (9kx12). One can not count the income of any of the 11 properties. This seems less optimal.
Maybe one can assume 50% property has no rental income? what is a more reasable assumption?
