}Runs the site's construction loan sizer on your project: the HUD 221(d)(4) loan (lower of 87%/90% of cost and the 1.15/1.11 coverage test, with HUD's construction-interest estimate and upfront MIP), the bank regulatory ceiling (80% of value and 15%-of-value HVCRE equity, plus your bank's loan-to-cost if given) and, if you give its loan-to-cost, a debt fund. Returns loan, binding limit, equity needed and interest.
| Argument | Type | Description |

| bank_ltc_pct | number | Your bank's own loan-to-cost policy, percent. Omit to see only the regulatory ceiling. |
| fund_ltc_pct | number | Quoted debt fund loan-to-cost, percent. Omit to leave the fund out. |
