@John Carbone how did you arrive at a revenue multiplier of 10x to arrive at purchase price?

I want to start in single family residential rental space, the strategies I intend to implement are house hacking and the brrrr method for a good amount of deals.

Many of my lower-income tenants do not have a credit card with $800 available credit.I plan to get away from both of these and implement an in-house system this year.  

Find an expert, such as Thomas.I wouldn't recommend it to get into your first property as there are much better 0 down strategies out there that can equally produce an infinite return while not requiring you to tie up any of your own capital.If implemented correctly, it can generate great wealth for generations.

The baseline rules are set by US EPA and US Army Corps of Engineers, then many states implement them and add their own more restrictive regs over the top.

We may see a recession in the coming 24 months if the Fed hikes rates sharply to curb inflation (this has happened like clockwork 3 times in the past 30 years, each time with a different Fed president at the helm - they all follow the same practices, it is just a matter of timing & implementation), but due to demand and the strength of the housing market, we may see at most a stagnation in prices, not a decrease, and then the march will continue up for real estate.

Not sure why this is being implemented and how they define it.

You can can save a little of that PM fee just by implementing a few simple processes I have fine tuned over the years of managing my STR's in Denver. 

And the end of the day, you still need to devise and implement a marketing strategy to get connected with the seller, which will most likely also come at a cost.

I'm sure you can find a member that is or has implemented the exact strategy your looking into.
