I was working with an agent last year and making offers that were 100 percent of similar comps (not even as low as 70 to 90 percent).

Welcome @Sartaj Ghai,Sounds like you are off to a good start and have the right long term mentality to go far with this!

I'm a CPA and full time real estate investor, have flipped hundreds of properties and own a rental portfolio (both short term and long term).

Home Paid in Full and will become a long-term rental.

Having a separate account to hold security deposits is a good idea.Having another account for business operations is also a good idea.There is zero risk in opening a bank account and it doesn't take that long so you can do it now or do it later.Good luck

If I could choose between earning $5,000/month from 10 doors, or from 5 doors, I would pick 5 doors all day long!

have been keeping me busy for the last 10 years or so.

However, he starts to talk about how you may sometimes overpay for a property because you are not necessarily worried about what the property is worth today but about the “long-term play.”

or as long as you have any percentage to be included for the "Funding Fee" to carry?

The bad experiences are painful but pretty much all real estate investors that make it over the long haul go through them all so good to knock them out early!
