My best advice would be to read through the contract carefully (builders usually have their own individual contract that's written for them and is leaning heavily in their favor).

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.

i do think it's challenging, though, for a brand new investor with zero experience to jump right into a huge rehab with a contractor they've never worked with before.the contractor might want a larger up-front payment to mitigate their own risk, and they're not going to be interested in any kind of fancy nonsense like a 'penalty' when they know a new investor has never managed a large project before.i have also found that some contractors, including reputable ones, don't even want to share itemized bids because they just don't want to have to argue about the individual line items. 

@Jordyn Gegg - I have a PM company that oversees all of my individual LLCs.

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. 

The home sold for 135k to an individual using a VA Loan.

While my insurance charges are relatively low each year given this is a condo, I learned to better assess who is behind budget planning at the HOA level for all of the units for roof, cleaning costs, basement improvements (shared by all units), given this was run well by one individual.

My name is Eli and I’m interested in doing fix/flip and BRRR’s I’m glad to be apart of this amazing community and can’t wait to connected with other like minded individuals! 

Unless you live in area that has many ADUs already built that have been sold with the home or as individual parcels.
