Plus with each new round of investment (to replace the previous) there should be less risk involved so the price (ie interest charged) should be lower. The one caveat is that the underlying assumption is that things keep getting better. If you hit a serious bump in the road, you might be scrambling for funds and end up having to accept a deal which is more taxing than the previous or worse, find the investor decides to take over the property (all depends on how finance agreement is written but it is common for there to be a clause allowing investor to take ownership should you fall foul of payment arrangements). Been following your adventure here with interest and wish you all the best
