the only one to ask this question to is your supervising broker or the owner of the brokerage.if your only wholesaling to make bigger money than a commission then logic would dictate you have to be untruthful to the seller and or buyer to the value of the property.. that probably goes against the rule of ethics.IE your going to assign contracts that is.if your going to close..

My rule of thumb is no more than 10% of your nest egg in any one deal. 

It's called tracing rules in the IRS lingo.

You will rarely find something at the 1% rule.

My rule of thumb is as long as the cabin is within a 15 minute drive of either the attractions in Gatlinburg or the attractions in Pigeon Forge, you're in good shape, just buy where the best deal is, the rents and occupancy rates are going to be comparable. 

Many folks on here subscribe to the 1% rule where your monthly rent should be at least 1% of your all-in price.

Two rules apply:1) The cost of the replacement property must equal or exceed the price of the sold property (less actual selling/closing costs).2) Seller must reinvest All of the cash received from the sale of the property, to totally avoid taxes.  

Keep in mind if you are going to purchase the property in an LLC there will be different rules.

I use that 100x rule as a way to analyze a property super fast.   

In my market, I like the ARV to match the 1% rule, and typically think borrowing up to about that is a good mix of being conservative, and getting some cash flow.
