1025 - gba or GLA?

[Useful Pappy]

Posing this question again. Page 1 asks for GLA but rental and sales grid asks for gba that means the entire area of the basement. It's confusing. Is there any justification to use GLA in sales grid? If subject has a garden unit and a comp has a finished basement but no kitchen how do you adjust? In my market in Chicago lots of owners rent out gardens even if not legal. Some are legal some are not and it's difficult to determine that. Thoughts?

I find it a flaw in the form or maybe my software in separating GLA and GBA. I have to force the changes in the form to make it clearer. Can be frustrating.

What do you mean force them in?

gba that means the entire area of the basement.

Gross Building Area (GBA) is the footprint of the ground floor.

Maybe your software can overide certain fields. I still don't know how to do it in my software but I manually try to change the automated transfer of GLA from the sketch in certain square footage fields where I want it to have GBA. Have to look at my report carefully to make sure of what I'm trying to convey.

That is not how F/F define GBA. For GSE work one should use the GSE definition

It sure what you mean by that reply. The GSE definition of GBA has existed for many years, and is often ignored by appraisers. Over the past 10 years I looked at a lot of 1025 reports and few of them reported the GBA correctly

Gross Building Area​

The gross building area

• is the total finished area including any interior common areas, such as stairways and hallways of the improvements based on exterior measurements;
• is the most common comparison for two- to four-unit properties;
• must be consistently developed for the subject property and all comparables used in the appraisal;
• must include all finished above-grade and below-grade living areas, counting all interior common areas such as stairways, hallways, storage rooms; and
• cannot count exterior common areas, such as open stairways.

Fannie Mae will accept the use of other comparisons for two- to four-unit properties, such as the total above-grade and below-grade areas discussed in Gross Living Area, provided the appraiser

• explains the reasons he or she did not use a gross building area comparison, and
• clearly describes the comparisons that were made.

Suggest you be consistent. If your comparing triplexes with basement units, then you compare grapes with grapes. GBA is a safer measure, IMO.
