Using IUL as emergency loan. Is IUL a good option in the long run with my plan?

Me and my husband are both having stable income thru our full time job. We also want to invest, start a business and having passive income. Our plan for the next 5 years is to open a property management company. Buying houses and put them up for rent. So far we’ve saved enough to buy a second house and will refinance to buy more. My biggest concern about doing this is:

1) What if we don’t have tenants or tenants failing to make payment on time for several months.

2) Bad tenants destroy the property, cost of fixing and remodeling the house

Because we ONLY HAVE ENOUGH for a down payment for this 2nd house and an extra 3 months of mortgage payment ( hopefully can rent it out in less than 3 months). To cover these risks i’m thinking about opening an IUL account, and use the cash value and take their loan as an emergency loan to pay for mortgage and fixing costs. Is it a good idea to do so? Please give me some advice.
