Does not affect your debt to income for future loans in the mortgage industry (auto loans could look different, but i would think similar so hopefully no worries there). 

Eliminate debt, establish a budget, and save.

so, you're maxing out debt service which makes it tougher to cash flow.with that said, no matter the purchase strategy, you should always make sure you're using actual numbers, and not random assumptions.for example - some people will throw out '10% for capex.' 

They have made major sacrifices and in most instances they have sunk fortunes into their portfolio to pay down the debt. 

I imagine the only way it would be possible is to do the bulk purchase in cash, sell off a couple and then put debt on them?

Partnering with private equity firms or debt funds provides access to capital in exchange for structured investment opportunities.- Revolving Credit & Liquidity Management:Instead of taking out separate loans for each property, consider portfolio financing and cross-collateralization strategies to streamline funding and improve cash flow.- Creative Financing Solutions:Options like subject-to deals, seller financing, and syndications can lower capital requirements and increase your purchasing power while providing flexibility for properties with complex financial situations.4.

It's the concept of buying the debt attached to the mortgage rather than buying the house. 

Speak with lenders - and consider that although they might agree they could lend to you today - they might not be able to when you need the loan.Unless the existing debt has no due-on-sale provision, there will always be a risk of the underlying loan being called.If it were to be called due:1.

I do not possess any special list.
