I have seen many a gorgeous historic home in fine condition be assaulted and battered in this manner in the more chic and expensive areas near me, and it is something done usually by a contractor who has no architectural literacy about these styles.

I'm assuming the developer has already paid for all of the soft costs (architecture, permitting) before you, the investor comes along. 

Instead, they miss the cloth or aluminum wiring and poor circuit allocation and instead show you with their fancy plug that "polarity is reversed"; or the always arbitrary "the roof likely only has 5 more years left max" because they see a 3-tab shingle from the ground and completely miss hail/wind damage on a newer architectural shingle citing its "lifetime warranty".

Based on my calculations and preliminary research, I have found that the Bay Area offers good returns from developing land, although acquiring level land and obtaining permits can be challenging.I have a few questions:1) Is it recommended to purchase a complete house plan from online sources like ePlans or similar websites and then customize the architectural design before submitting it to the municipality?

If this is a relatively small project, then you can ignore the rest of my post.If we're talking a big project, like at least mid six figures, you will probably need architectural drawings first, and permits. 

Not luxury to live in, but a classic piece of FLW architecture.

It's tough for me to answer on a learning curve question I went to high school for architecture and college for construction management and I've never personally flipped a house, although I know how to budget and schedule it.

Assets identified in this study include:Concrete paving and paversFencingEquipment padsConcrete sidewalksLandscapingThis engineering-based cost segregation study included the following methodology:Physical Inspection through a site visitDocumentation review including architectural plans, accounting records and construction documentsA cost analysis which utilizes engineering principles in order to allocate costs to their applicable asset classificationsCalculation of the depreciation schedule using MACRSAs a reminder, bonus depreciation started to phase out in 2023.

The underlying architecture of these models makes them best for chatbots & translators (matching word meanings/uses across various languages and translating based on positional/usage probability).I understand in 10 years there might be an Ai that can do this, but right now, these tools are useless for achieving anything of substantial complexity (meaning anything from medium-large coding projects to properly valuing a home, or even calculating the proper $/sf avg in a zipcode), so I don't understand why you repeatedly advocate for their efficacy in this REI space?

Look for a small/mid size local bank that specializes in this, they will detail what you need, survey, building permit, architectural plans and a builder contracted for starters.Or when you're ready to subdivide/redevelop you just sell to a builder and have them split the lots and transfer title to you for your smaller lot, he keeps the others and let him mess with the utilities and building.
