I am new to the BRRR approach, but I am very interested in implementing it. 

I just rented out the condo I moved out of for one year and then sold, but the only reason I would say to sell vs. rent would be if there are any condo rules preventing you from renting/anything that could significantly jeopardize your cash flow.

What's to prevent them from attempting to do so?

That would mean something like, if we get 440k for 5 properties, we would pay back 600k over 15 years, at 40k a year (some of the NOI would be held alongside the initial buffer for emergencies until a certain threshold is reached, after which excess of that could be returned toward repayment).While this is an excessively long term investment in terms of real estate not going into a funder's direct portfolio, am I missing something crucial in my calculations or expectations of realized returns that would prevent me from finding someone willing to make this type of deal?

@Maria Luna call 10-20 local community banks and explain what you are buying plus the business that you will implement and you should find one that will lend for you.

So far, I know:- find a good deal, with opportunity to add value- assemble a deal package showing numbers (current state, remodel, after remodel, returns before and after refi)- for the first deal or several I will have to accept I won’t be able to take as large of a portion of equity as I’m a large risk for investors- attend meetups feverishly- be active on forumsWhile this all seems intuitive, I have a mental road block preventing me from accepting that I will be able to raise funds.

Having life insurance prevents you or your heir in becoming motivated sellers.You can use life insurance to offset estate taxes as well since your heirs get life insurance payouts tax free.And lastly, there are life insurance that can be structured so that if you don't become sick or you don't die in 30 years, you get all of your premiums back.So, YES, life insurance STRUCTURED PROPERLY is a VERY good idea. 

What I was going to say was that when I turned 54 I had a brain annurism and a stroke and have not been able to walk for over 8 years and they happened two days before my scheduled preventative surgery and I never anticipated that because I was in perfect shape and a Chiropractor told me to get a brain MRI. 

In addition, there was a hamster/rodent box in the garage (We have a no animal/pet clause), she had sealed up the vent opening under the side garage door that is there to prevent carbon monoxide poisoning from the gas water heater/gas heater/blower and the gas dryer that all reside in the garage and the last thing is she had put cardboard covering in the garage door windows and the side garage window to the block sun from coming in.I am told the gentleman that is staying in the garage is the boyfriend of one of the daughters that is a tenant.
