My contractor has one credit card for all of my individually owned buildings (jointly not multiple cards) and one credit card for the building I own in a partnership.

Break down your rehab into individual jobs, for example get a electrician for electrical work, a plumber to repipe the house, a dry wall guy to close out the walls, etc.

The section continues, “… Bed and Breakfast establishments, boarding homes, dormitories or multiple units, or any other similar lodging arrangements are specifically prohibited.”Section 3 – Commercial Use – states, “…no part of a Lot or Dwelling shall be used or caused to be used or allowed or authorized in any way, directly or indirectly, for any business, commercial, manufacturing, mercantile, storing, vending, or other such nonresidential purposes…”.

While the IRS does not mandate a physical site visit, the IRS cost segregation audit technique guide (ATG) does suggest conducting “field inspections.”It’s important to note that the ATG is not an official IRS document.It serves as a guide and cannot be used, cited, or relied upon as an authoritative source.However, the recommendations in the ATG are worth considering.According to the guide: “A field inspection is recommended to document the physical details of the building, type of construction, materials used for construction, the assets contained in the building, the size and types of building systems, and any land improvements that were included in the purchase of the property and the condition of that property at the time of purchase.”So while the IRS does not require a site visit for cost segregation studies, following the guidance from the cost segregation audit technique guide can be beneficial.There's this thing called Hierarchy of Tax Authority that CPAs and Tax Attorney's reference.Let's not get too carried away with comments like, It serves as a guide and cannot be used, cited, or relied upon as an authoritative source....

Quote from @Brody Veilleux: As far as I’m aware, FHA loans are only for individuals.

If individuals and/or LLCs are the beneficiaries, then it is doable.
