100% financing to Purchase a Commercial Building? It's possible with an SBA loan if you're an existing business.
Some banks are now offering SBA loans to finance 100% of a commercial space for your business if you occupy 51% or more of the space.

If your business is spending capital paying for its lease each month.   Why not consider a Rent Swap?  If you purchase the space, you may be  able to reduce the monthly expenditure and at the same time, build  equity.  Preserve your capital to use toward other business expenses.   When a loan amortizes over a 25 year term, the monthly loan payment can  end up being much lower than your monthly lease payment.  You can also finance additional working capital for  repairs, renovations or newly updated equipment.  Working Capital SBA  Loans are often limited to a 10 year term.  In this case you can blend  together the working capital portion of the loan together with the loan  for the building and stretch the entire total over a 20 or 25 year  term.  

Your business must have been active for 2 years or more with  corporate tax returns showing growth and at least a small profit.  Banks like to see a 1.2x Business DSCR.  This should not be  tough for newer businesses who are still in a growth phase.  Your  business must occupy at least 51% of the building space.  If there are  other businesses leasing in the same building, you just need to be sure  that your space is larger than their space.   Another idea, would be to  create a small separate space with the working capital you can obtain  and rent it out to another business.  You can collect rent and use it  toward your loan payment for the blended commercial building/working  capital loan.

If you are not able to purchase the current building you are leasing,  you can still take advantage of this program.  Commercial spaces that are similar or somewhat comparable to the one you  are renting can be financed.  It may be worth your while to break a current lease early  to take advantage of this program.
