@Jacob Hrip congrats on taking steps to hitting your investing goals!
1st, lets talk about equity in your homes. You have some, but not as much as you think.
Primary Homes - most banks will easily do 80% of the value of your home, some will go up to 89.9% loan to value (LTV). Some credit unions will go to 85%-95%, but there are just a few that will do 100% loan to value! Check out Tower Credit Union as one option for 100% loan to value. Rates will range from Prime (currently at 7.5%) to Prime + 4% (11.5%). The higher you go on the LTV, the worse the rate will get. Also, some helocs will offer Interest Only payments, some that go above 90% LTV may ask for 1% of the outstanding balance or 1.5% of the outstanding balance. These payment options can get up there! Shop LTV (or cLTV which is combined Loan To Value, basically your first mortgage and 2nd mortgage combined loan to value), rates, payment terms, time to close, and draw period (how long you can go into and out of your heloc).
Investment Property - Most banks and credit unions will tell you that a heloc on investment property is not possible. TD bank is the only major bank that I know of that does helocs on investment properties, and last I checked they would only go up to 65% of the value of your home. As a broker, I do have access to about 15 companies that do helocs on investments! Most will go to 80% of the value of your property, some limit to 70% max. Rates on i
Heloc is a great way to come up with down payment money, but i would not do your rehab out of a heloc. You want this to be your backup plan if things take longer than anticipated, you do not want to dip into personal credit cards so i would use a heloc to help with down payment but try to keep a nice available balance on a heloc as your insurance policy.
Rates will usually be in the Prime + 3-4% range if you are trying to max out how much of a line you can get.
Private Money vs Hard Money:
Primate money is negotiable. Hard money is usually "take it or leave it". Hard Money Loans are generally speaking institutional money so they make the rules and you either like it and take it, or move on to another lender. You generally cannot negotiate.
Hard Money will usually finance 90% of your purchase price and 100% of your repair cost up to 70 or 75% ARV (after repair value). Many hard money lenders will offer the best terms once you get 5 "completions" or "exits" from hard money loans (sell the property or refinance out). Most hard money lenders do not have prepayment penalties and most will be in the rate range of 10-13% with 2-4 points as upfront cost.
Private Money is whatever you can work out! 100% financing, no payments, financing in extra "cash out" money upfront so you can do a rate/term refi once you pay them off... equity splits, no experience... whatever you can work out!
Because private money can be so flexible, it is often times better than hard money loans but not always. Private money may be cheaper, but may be more expensive if they are doing something that most hard money lenders wont do.
BRRRR out of your flips is great way to keep some of your properties! Many lenders will allow you to do a BRRRR and take cash out, even without owning the property for 6 to 12 months. Setting up your purchase money loan to allow better refinancing is advised when possible. (Get 100% financing plus cash out from your 1st lender would allow almost all lenders to do a rate/term refi once your rehab is completed. You can go up to 80% LTV on rate/term refis with some lenders!).
