U can do 100% if you want but you should have plenty of cash on hand as well. 

I am glad things worked well for you over the years. 

(well you said "negligible".

I bet that essentially no one is starting new construction projects, which bodes extremely well for owners 2-4 years from now.- Prices for insurance policies will never go back down, but it is not unreasonable to expect costs to rise at a more predictable pace from here.

If they're cash flowing super well, why sell or take out a HELOC? 

I am learning in the real estate business as well but in the Kentucky/Tennessee Market!

We have a niche market due to the hospital and university which has pros and cons but my properties have continued to perform well for me.  

Quote from @Stacey Wells: Hey everyone,I’ve been researching different funding options for real estate investments and business expansion.

Then, I would share with them how you manage properties and what your expectations are for them as well as you - essentially explaining how you work with people renting from you.

Explore insurance options as well!
