after they cash out 1.4 or 1.6 billion usd they need to declare such money back in the u.s. and subsequently pay taxes. 

I subsequently set up the property for Airbnb rentals and began generating rental income.

If that's more attention than you want to devote to the enterprise, start looking for something else to do.- You want a 5-bedroom duplex.  

There is a lot of money to be made or lost in this enterprise.

They have an incentive to ensure none of their units are sold for below market, it'll affect the sales price of all subsequent units too.3.

I would like to follow the BRRRR strategy, get my money out of the deal and subsequently purchase another investment property. 

What are some of the more legitimate, often used, loan types for subsequent properties?

A lot can change in just four years (as everyone on the planet who lived through 2019-2023 knows).Five years ago, BRRRR method investors were generally limited to conventional loans (under government-sponsored enterprise, or GSE, rules and limits), bank portfolio lenders, or other niche options like private money (individuals).

@Doobie Sims, there are lenders that allow for delayed financing and who will use the appraised value before 6 months on a cash out refinance.So if you buy a house for $126K and you do a lot of work on it, it appraises for $250K, the lender will use the $250K for loan to value purposes.The 6 months or 1 year guidelines are for lenders that do qualified mortgages (QM) mortgages who sell their loans on the secondary market to government sponsored enterprises (GSEs) such as Freddie Mae and Freddie Mac to replenish their cash for more loans.Non-qualified mortgages (Non-QM) can decide to adopt all of some of qualified mortgage rules to mitigate risks but they don't have to since non-QM lenders sell these loans to different investors on the secondary market to replenish their cash for more loans.

So the cash I used for the house missed the stock market crash and the subsequent rebound.
