If you can continue to renovate the 1st and 2nd floors, that is when I would update the plumbing and copper in those units.We may have a plumber who would work in that area...happy to share a contact with you.

I bought a wholesale property last January using a hard money loan with 80k in renovations.

Then as units become vacant, then do other renovations.

Any shifts in buyer demand, renovation costs, or financing that I should keep an eye on?

That renovation included everything inside the exterior studs (all-new heating, electric, plumbing) and exterior siding.

When someone tells me that "you won't have repairs or cap ex for a while since the seller just renovated it"... well that property is -$300 to $-500 a month from repairs called in by the tenant most months.

I paid for the renovations with cash and now since my credit is 2 points below I can’t get money out???!

We have been renovating each apartment 1 by 1 as tenants move out and renting the apartments for $1,800 ($18,000 projected gross monthly income).  

This is how you do that-- be properly equipped.I can go deeper on the renovating side, there's a ton to pay attention to.

Depreciable basis will be purchase price + renovations
