I've only had one listing transaction from my BP leads.Most are complete noobs or have limited REI experience with a rental or two.

All real estate transactions in SC must be conducted by real estate attorneys.

Now, if you've already set up LLCs per property, then yes, have at least 1 checking account per LLC.For people who own their properties personally, keep personal accounts that are exclusive to RE activities so all of that activity stays separate from other personal transactions.

. $360k equity (based on your estimated loan balance and estimated transaction costs if you sold, this is not calculating capital gains taxes but that would reduce your equity down to about $310k if you sold without doing a 1031 exchange). $8k cash flow (this will increase over time because you are in an appreciation market). $6k principal pay down (based on your current loan). $20k appreciation (based on 3% which is conservative, 4-5% is the historical average).

This would be a prohibited transaction since you're a disqualified party and anything you already own (your LLCs) is part of that. 

nothing new  or novel  in most transactions.. 

No, I use PriceLabs which is dynamic pricing and adjusts prices on both platforms daily. 

There are far too many regulations, the transaction is a much longer process, and we are talking about someone's biggest purchase.

If they want referral, I can give some names, but they can take a look at themselves too.So in reality, buyer agent is doing like transaction coordinator only.

This means there are no checks and balances to ensure all transactions are entered correctly.
