Sorry for the time lag on this. I wouldn't bother putting my two cents in on this but I think you need to know this.
If the transaction amount is $250,000 or less, you have a residential appraisal requirement, in which case you need an appraisal for each legally described unit. That might be eight units of four two-unit buildings or four two-unit buildings, depending on the highest and best use and how the properties are legally described. Highest and best use of the property might make things different, but I'm assuming here that HBU is residential single-family or multi-family.
I'm thinking it isn't too likely that the transaction amount is $250,000 or less, so you are dealing with a commercial real estate loan...income real estate if the developer is hanging on to the units and becoming landlord, or subdivision if the developer intends to sell the units after completion.
If he's turning into a landlord, you need an "as is" value which is derived via capitalization of a stabilized income stream or present value of a cash flow. You might also need an "as complete" and "as complete and stabilized" values. I'm a little fuzzy right now and too tired to look it up, but those last two values might be bank policy driven rather than regulatory agency driven. In this scenario someone might be able to argue that the "multiply by 4" value is the same as a properly derived value, but it's not acceptable appraisal practice to get to the value this way.
If the developer is going to sell off eight units, either in bulk or in any combo of one or more, it is considered a commercial real estate subdivision loan in which repayment of the loan is dependent on the sale of the units. Again, I'm fuzzy on what you are required by the regulators in terms of values and what you might be required dependant on bank policy, and the state of the site/s might make a difference. The following list is (I think) fairly comprehensive of any subdivision/multi-unit scenario, so you could pick and choose depending on the project.
- as vacant, unapproved and unimproved
- as vacant, approved but unimproved
- as complete (infrastructure only)
- as complete (infrastructure and vertical)
- as complete and stabilized (if lease-up required)
- value of each type of model/unit
- gross sale proceeds
- net sale proceeds (present value of the sell out) - this value should reflect the value as of the effective date of the appraisal, and theoretically, if it is before any approvals or improvements are in place, it should equal raw land value.
If you need me to find the regs to support this, let me know. Too tired tonight but can dig when I have recouped :-)
