If i can, is it fesable to ask the landlord that lease payment will be paid monthly and the Property purchase amount will be paid within the 24month periode?

If you do be prepared to have a rate of 9.50% or higher which in most cases would be a higher payment than if you simply refinanced and lost the 2% rate.You may also have road blocks with a HELOC that a cash out refinance would not have due to cash in hand and one loan. 

I assume I should be looking for low down payment loans.

With the 5% down, our mortgage payment would be about $5711 a month.

Let’s say you finance a 750k loan your payment will be around $5k/mo just P&I.

To convert some of this income to self-employment income simply for the purpose of then making contributions to a retirement plan is generally non-beneficial. 

@Ben GleasonNotice of non-renewal.

And a second one for $7000 where I got about 3 months into it and did the live calls but could never get my questions answered and finally they were just pressuring me to buy properties that were several million dollars and telling me I needed to figure out how to borrow $700,000 or more dollars to get the down payment and I just quit.

Once the lease is signed and they collect payment, they walk away.

Details: Current mortgage is $480k at 2.625%, $3,400 monthly payment.
