@Jose Leon III. Congrats on getting started.
Thought I'd share a few questions for your further consideration. I'm assuming your 30 year interest rate would be a bit hire, but I'm sure you'll adjust accordingly. didn't notice any information on the subject property specifics / condition: i.e. Roof, Foundation, etc...? Do comps provided have updated kitchens, bath, flooring, etc...?
Couple pieces of advice - I suggest you also factor in holding cost, property maintenance, property management, insurance, vacancy, etc.. as well as taxes. Here in Grand Rapids, MI, actually Michigan in general... the property taxes are the biggest error most potential B&H owners make. I often see calculations done using the "homestead" tax rate, vs non-homestead, which can be 1.5-2X the normal rate. Grand Rapids has an extremely low vacancy rate, one of the lowest in the country in fact, so rates are going; however, so is the cost of each subject property. Feel free to send me a spreadsheet with your numbers, and I'll do what I can to provide some feedback.
Exciting times... looks like you're moving forward. Jacques
