Evaluating a property for personal residence and funding ideas

[Tim G.]

I'm looking at one tomorrow. Comps are all in the 440-490 range completed and this one is in the low 3's right now in need of no structural but a full rehab. Landscaping, windows, floorplan, kitchen, bathrooms etc. Its a 3/2 with 2x the sq ft of the comps with several extra rooms I'm guessing not counted as bedrooms due to the lack of a closet.

This is a house I want to own, I was getting pre approved and haven't yet completed the process yet. I want to make an offer, just wondering what my options are on a property that will close in days and currently without guaranteed funds. I'm looking for the best options to lock this in while I race to get funds. I can get approved for the purchase amount I have money to put down the place can be financed conventionally.
