Marvin, I referred t this as a skinny deal because based on my experience, the % of potential profit is small in relation to the size of the deal.
I realize that in dollars it seems like a lot of money (if you're new to the game) but I have learned to go in to my deals with a conservative mindset.
While the ARV estimate is $600k to $625k, I would expect to sell at the low end of the range because the house is "market weary" and we are entering the winter season.
I would also expect to invest more into repairs & renovations than $25k because inevitably something else always comes up.
And lastly, when a deal has monthly carrying costs of $3,000 it doesn't take long to drain the profit bucket.
So for me, this is a skinny deal. I would keep it simple by tying the property up with an option, then I would market it aggressively with the most attractive terms that I can arrange.
If someone takes the deal...great. If not, I suspect you will at least add to your Buyers list for future deals.
Over the past 33 years, I have had many deals that didn't close but served to introduce me to Buyers & Investors that I went on to do deals with later.
For me, it's a "win" either way.
