I put an offer on a house for STR and I'm freaking out

[Isan Monfort]

The offer was for $465k 5% down, the counter $475, I think its over priced, I should probably had offer less from the get go. However Airdna says it'll produce $135k year, but with interest rates rising my monthly expenses would be close to $5k/mo, or $60k year.

The house still needs $30-$40k, pretty much all the money I'd have left, for a few renovations if I want to take the nightly rate high enough to compete in the area and have a chance to reach those $135k. 

Also afraid to be all in and launching in the begging of the winter. Apparently the coldest winter in the history of NY is coming. 

Do the numbers sound good enough? 

I'm thinking of getting several new credit cards at 0% the day after closing on the house and max them out so I can do the renos + furnishing. All in baby, but it's scary AF
