So far, I have been targeting probate leads and using bandit signs as a method of marketing.

When grandma is talking about brrrr, SFR, and MFR then it is time to be a bit cautious.

hello bp.. using the brrr method is one still capped at 4-10 loans when looking for refinancing out?

You might want to learn advance creative negotiation methods.I don't care where you go in the US, there are deals to be made if you know how to negotiate them.Maybe some ideas on creative methods will help you find what you are looking for.Try, Hybrid offers, delayed settlement, principal mortgages, vertical break ups, take backs, study periods, subject to public auctions, friendly joint ventures.Control and Roll is a great way to sell properties you don't own and to make fantastic profits.Charles

I found the website from the podcasts and unknowingly have been using the BRRRR strategy termed here in the forums.

@Mike D'Arrigois also right when he says "This (BRRRR) model only works for more distressed properties where you can buy at a deeper discount and add more value".Successful Wholesalers are adept at buying "at a deeper discount", so if you don't want to put in all the effort that they do in order to get those bargain properties under Contract, then look for THEM (value-for-money wholesale Sellers).

I've heard some people say you could got a traditional mortgage to start off, but I've also heard that people are shying away from this method (traditional mortgages are dead?).

When done correctly this method can provide liquidity, guaranteed returns, security from creditors, disability protection, and finally a death benefit.  

I'm seriously considering using the BRRR method to obtain some rentals, but before I pull the trigger, I'd like to know some of the pros/cons other BP investors have run into with this strategy?

The quit claim deed worked and we are not under construction to BRRR method.
