@Marcus Hill - I look at the HELOC as a checking account. When I refinance, I am pulling all the money I can out of the HELOC that I paid in to reimburse for any money put out to purchase and renovate the home. All rent that comes in from my tenant goes towards paying off the HELOC. When I need to pay my property taxes, home owners, any maint. issues, etc., I use the funds from the HELOC to pay for them. If my payment on my HELOC is $600 a month and I am paying the total rent of $1,100 a month towards the HELOC, I am paying my principle down faster. The faster you pay down the principle the faster you pay it all off. The advantage of the HELOC is that as I pay down the principle, I am building more liquidity in the HELOC in case something else comes up or I need the money for something. The HELOC can have a higher interest rate than a fixed rate conventional mortgage, but as you pay down the mortgage, you can not access the equity without refinancing or getting a HELOC.
The home I just purchased I got for $79K and it appraised for $95K before any renovations are made to increase ARV. It had been on the market for half a year needed some structural repairs, new septic tank, crawl space issues, and was in need of cosmetic updating. I knew the costs of the major repairs before putting in an offer, so I was able to drive the price down as the owner just wanted to move on from the property. I did find some unexpected repairs that are going to cost me $$ to fix, but that is always the case. I did budget for these, but it still hurts. This is my 4th investment property and I am learning a lot as I took on a bigger renovation with this one than I had with any others.
