this isn't an option for everyone based on family situation and lifestyle, but I know multiple people who have sequentially house hacked their way to a portfolio of 5-15 units in 5-10 years simply by using their monthly housing payment.

., this I think is longer term implosions as I am seeing people who absolutely should not be buying a home as they have no money buy them sub-to because of little down payment and will eventually lose the property and that is when many whose mortgages are still on the property come out and sue.

Or do you go for cash flow only?

When they don’t share the numbers proudly, it is usually a negative cash flow situation. 

Hello , I need some advice for a friend of mine - so my friend is being serviced with a eviction notice for non payment, the notice is dated for Jan 1st - jun 1st quoting 5,000$ but her rent has been paid by housing and was up to date which she has proof it’s paid.  

My plan is to sell my current house which will give me around $300,000 and in the next 2 years me and my wife will save another $100,000 which come to the total of cash we have in hand is $400,000.

I usually ask for some form the rent roll/rent ledger showing payment history and some form of proof of payment (I'm a bit paranoid) for the last two months (deposit receipts, bank statements, online receipts for payments made online rent portals, etc.) 

But if you plan to scale up, aren't you talking about $1mm to $2mm upfront cash to support your deals, prior to lenders? 

There have been several examples of $1M+ listings that are still receiving multiple offers, and many for all cash. 

But what I never hear anyone discuss is how the payments on the HELOC, whether interest only or principal and interest,  factor the overall cashflow and return?
