Doing the numbers on a commercial property value calculator, without debt service I will be at at a valuation of $3,026,400. 

Will you be using the BP calculators (or alternative) to determine "pure" cash flow so you find a deal that really works.

BiggerPockets also has a calculator to analyze deals, and I highly recommend you start this as soon as possible, even if you are not ready to buy.

To be clear, I am running comps to help calculate the ARV. 

That means the rate will be fixed for 7 years, the payments will be calculated on a 25 year amortization, and there's a balloon payment at the 10 year mark. 

Im not sure I completely understand what you're trying to calculate but I would go about it using Excel or Google Sheets and create a "master" and a separate sheet for each property. 

I've calculated the cap rates and they are all generally similar (~4.5%).

Hi @Kent Kettell, assuming you're running the numbers on your end, any loan offer that enables you to acquire the asset given your level of cash reserves and reach your target ROI at the expected project duration, net of financing costs.If you don't already have a useful calculator to assess cost and profitability associated with fix & flip projects I'm happy to share a copy of ours!

HELOANS are an option, but you have to calculate your blended rate and compare that to a new first lien.

We have a detailed BRRRR cash flow calculator tool we share with our clients to help assess these types of projects.
