Kevin, Wether the banks will entertain your asking for a WLOC (working line of credit)depends on a few factors such as: how long you’ve been doing this, how stable has the cashflow been, how many deals you’ve done, your assets, etc. When you say that your income from wholesaling is “sporadic” just how frequently are you putting these deals together? 2-3 a month? or 1 every 2-3 months?
Every bank is different! Some may only require a 1 page cash flow statement and others may want a full blown business plan. In either case the bank wants to know that you have a real business and not a hobby. You have been investing for a while and your properties cash flow you will be in good shape and at the least you will be able to establish a line based on the equity in your properties. After the bank is satisfied with your performance then they will give you an unsecured line. But, as I said before every bank is different. Meet with them first (commercial department) and ask what they are looking for. I had one bank entertain my request but then never heard from them again. I went to another bank and they did not hesitate to give me money. I later found out the first bank viewed REI as a speculative business. However, if my business (or one of my businesses) was a property management business they would have given me the line. To them the property management business was a viable business. Sometimes it just boils down to how you present yourself (business).
