I plan to purchase a property needing renovations in order to use the BRRRR method which can help me purchase a 3rd and 4th property in the future. 

Thats the basics of the BRRRR method that is advertised around a lot.The usual restriction is the "6 month seasoning" period. 

I discovered that the current owner has numerous complaints filed against him from tenants and it paints a vivid picture of him being a slumlord(numerous of post are saying don't do business with this guy!).

If i use the brrrr method how long in to the loan should I refinance it

Can someone tell me all the methods there are for real estate investing and what are the beat ones and even personal methods that you use

@Sarah BridgesThe 1% rule is really just a quick sorting method if you have allot of options. it's not an end all be all for REI.If I was relocating and needed to find a deal I would try to understand the market first.

Just purchased a SFR for our family while using the house hacking method.

Personally I like the PnL method because it is cleaner and easier than 12-24 months of bank statements.

I have made numerous contacts and enjoy meeting new people. 

But I have read numerous stories of how investors got ripped off.
