Feel free to reach out when you're ready to have a conversation about what the financing will look like. 

It may be hard for the next 30+ days while they rant, rave, and try to make your life miserable, but then they will be gone and you will immediately notice your stress levels go down, you will free up a lot of time, and everything will be better.P.S. this is one of those situations where you may want to sweeten the pot.

If you do not plan to live there buy it as either as a Seond home or investmet.Second Home is 10% down - seller can offer seller credit to cover closing costs.Investment Home - 15% down - Selelr credit but ony 2% of sale price Max.Pull cash out of your primary or another property via cash out refinance or LOC for the down payment.Feel free to reach out if you have any questions.

your business will have it's own tax return depending on how you structure it and you'll get a partner return either profit or loss and that will pass through to you typically if you are an LP. if you are GP it's a little different. you also get the depreciation of the asset as a tax write off as well as interest expense typically. 

On the conventional side, one of the biggest lenders, I belive they'll give you a few days free, but if you need to extend over 5 days then it is 2.5 bps a day, and if you need a 2nd extension then they double it to 5 bps a day. 1.5 bps is VERY reasonable.

If our agent pays him via checks and bills us at closing, does this have any +ve or -ve impact on the taxes?

This way you wouldn't need to provide paystubs, W-2s, tax returns etc. 

If your LLC earns a profit on fees it earns from property management you will owe self-employment tax.
