Use equity for Rehab?

[Jim Sebring]

Buy and hold newbie here. 

I recently closed on a 3/2 in Tampa with existing tenants (lease ends next month - they are moving). This property needs extensive remodel. Costs should be approx 20k. 

I have 200K in equity on some other properties.  Should I pull out some of this equity for the rehab, or use my own funds for the rehab? If I use my own cash, it would take a long time, perhaps 4-8 months to complete the work. I'm OK with this as I can float the payments. Or,  would it be better to pull out some of my equity and rehab the place MUCH faster.  I dont like the idea of using a Heloc but maybe my thinking is flawed. Any help appreciated!
