As in two or three years living with this person whose shall we say lifestyle is so uncomfortable to you???

Problem is - the seller needs the cash to satisfy the mortgage + have funds to move to a new house.

A true DSCR product doesn’t care about your personal debt. 

The only PITIA paid from personal account is for a personal residence.

I’ve been chatting with a fund manager about our performing notes.He asked a question I hadn’t heard before...Would we be willing to buy any loans back if the borrower goes 90 days delinquent?

How can I find a way to make this work when I only have 20K of my own funds to put in?

They then decide if they are willing to list with the agent.If you have substantial capital and can close quickly, with cash, no inspection you might be able to do what you are suggesting.But a bank is incentivized to get as much as they can, with the least amount of hassle and they will believe their real estate agent before they believe you on numbers, closing time, availability of funds.

@Joseph MuleroTo boost your rent plan and make more money in the medium-length rent market, think about these steps: slowly add furniture to the new place while you stay in your current home, pick cheap furniture, use a credit card with good terms, look into loan options like personal loans or home equity credit lines, try out the market by listing the place with few furniture pieces, aim for easy-to-change furniture for flexibility, and talk to pros like real estate agents or home decorators.

If you pay back all the upfront capital needed to fund the deal, the return becomes infinite after that, so that plays heavy.  

You could get a DSCR financing on the 1st rental property you have to come up with funds.
