However, the tax free cash infusion we got from the live in flip has allowed us to buy WAY more properties than we would have if we would have just continued to do live in multi house hacks. 

Homes of this vintage will have knob & tub wiring and a fuse box (typically screw-in fuses).If you find there's fuses, then that's what you will have. 

@Marc CelestinI learned the condo fee for Regency village is 310 per month and it infuses all utilities.

At a minimum your replacement cost would be around $3600 per unit.Obviously, this would be cost prohibitive for most investments and so generally you see budgets that show capital accounts with large infusions staged over extended times.

The Lawrenceville neighborhood reminds us of Portland 10 years ago, infused with a charming mix of brewpubs, cupcake shops, and hipsters.  

Flipping is great for a cash infusion, but it is a job.

Where that is not practical I would record any expenses paid from a personal account as a loan or equity infusion from the owner so your records clearly show an intent for the LLC to operate independently from you the individual.

They're actively seeking $15M and upon that equity infusion will have the land to build the studios and sounstages. 

If you don’t like debt idea, treat Heloc funds as the capital infusion to LLC( capital account). 

I have successfully moved into the final pot infused wonderland and am working towards the end of my time living in the building.
