Assuming that no debt is involved, Is paying that cost necessarily better than paying the tax on your long term capital gain in the property?

You have a week and you have the cash to pay all the debts?

Sure the terms can be different as fixed and mixed rates can have up to a 2% fee for early pay down.

Question, can i use HELOC from primary residence to buy land somewhere else and be able to deduct interest that I pay on HELOC?

Example: when a potential seller insists on being given the price you would pay for their home over the phone.

I would pay Wealthability if I see that the proposal would indeed save us more than we pay for the fee. 

You won't pay tax anyway through that.

Do they take care of the place, pay rent on time, etc? 

This means that you will probably need to pay registration and filing fees in at least 2 states if you don’t buy CA property as a CA resident.Any lawsuits should be limited to the assets of the LLC and not your personal assets (assuming you run the LLC appropriately and the corporate veil is not pierced, some debate as to SMLLC).

This will make it a passive investment and you will not have to pay as much in capital gains.
