One thing that you can try in your area is do a google search for SMALL community banks. The ones with only a few branches trying to compete with the big boys. Sorry...this post became long with my answer!
I was given a name of a very small ( two branches) community bank near me. Spoke with the lending officer - and told him what I am doing, what I am looking for, and prefaced that with "I have been investing for years - but I need and will search until I find - a bank that understands what I am doing and will allow for a product that they might not have done before". When he asked me what I need to continue being successful- I told him "some type of line of credit product where you can send an appraiser to the house to verify the house value, and I will need financing for six months or so until I can sell the home, and will need the funds pre-approved so I don't wait with each house for financing approval. " Of course- his answer was along the lines of - "let's talk, and I am in a position to recommend to our board (of directors) any product that makes sense". Meaning...I am the one that suggested the product, the use of the funds, the time limit that I would need it for (for each project), etc. I also mentioned that the best homes I want to add to my portfolio - and will need a "standard" mortgage product on it - he really liked that statement. They are in the business of lending, and if I diversify with multiple homes - the risk drops substantially with any given house payment, with other wholesale deals also in the pipeline.
Now- I also have a portfolio of cash flowing homes- so it may be a bit different in that regard. But...I also had to give him my personal information, SS#, etc - so they know who they are dealing with. All they are waiting for is my 2015 tax returns to verify everything. I expect an approval within weeks of me providing the return. Everything up to this point he mentioned was good. They are willing to lend up to either 70% of the before rehab value, or 70% of the after rehab value - so I am the one that will buy the home, all repairs, etc - and pull my cash out upon finishing and getting the appraisor to justify the new value ( this was part of my risk reducing strategy for them). But- the 70% was their offer to me -other banks will have their own different criteria. This work's for me, since I am looking for a $500-1MM line of credit. I must keep recycling my money and have them refinance me with a 1st lien until the house is sold. Since the line is quite large - I can do many homes before I max the line out. Hopefully, before house #3-4-5 I will have house #1 under contract or sold. And my strategy is to rinse and repeat.
So...you never know financing opportunities near you until you inquire, meet with them, and offer them some type of reasonable business opportunity where they are not taking the entire risk. They may start you with enough for one house at 70% ARV - but when you prove yourself with them, it will be easier to expand over time. Each bank wants a client that always pays on time, and is selective in their investment criteria. That's what relationships are built on with banks. They won't just lend because you found a home- they want a well thought out plan for growth, a safe investment criteria and some risk absorbed by you - so they are not in 100% on any one project. A well thought out written business plan is a must!
I guarantee there are banks near you in NC that want to hear what you can offer. Remember - If it was easy - everyone would be doing it.
