From my understanding, the IDR plan will factor in my income and family size, making it more affordable. 

Unfortunately, there is no one size fits all approach.

They are all in decent areas.I like the program.They pay all or a large portion of the rent.The tenants take care of my houses and stay a long time. can i contact you John to get some advice on investing in MD for sec 8? 

An STR that is poorly managed may leave the PM without his or her portion of the income, but it may set up the owner to lose the property if that cash flow was needed to pay the mortgage.

Quote from @Bruce Schussler: A lot of Podcasts and Youtuber's say to cash-out refinance to keep rents balanced with payment; (PITI) then use those funds strategically to re-invest either in more real estate or just put into a high interest bearing account or money market account...Here's some of my thoughts and comparisons;Cash-out refinance with new loan so rents balance with payment:- The cash-out refinance is 100% tax free- The funds can be put into a money-market account off-setting a portion of the interest charge of loan- The loan balance gets eventually destroyed by inflation- The liquid cash eventually gets destroyed by inflation - The interest on the new loan can be deducted from the rent income- The refinance costs are 3-4% of the total- There is less equity in the property and LLC that can be attached in case of a lawsuit- The break-even on cash-out refinance with current interest costs on the new loan is around 12 years Vs.Paid-off property with positive cash flow:- The positive rent income is 100% taxable minus only depreciation and property tax- There is more equity in the property and LLC that can be attached with a lawsuit- The break even is not until after 12 years at today's interest rates- There is a rate risk in today's inflationary environment where interest rates on bonds keep rising*It appears to me that the cash-out refi is in the best interest for a property investor; (Dave Ramsey would strongly disagree!)

Assuming the ditch is a foot wide that's almost 14 yards of dirt, which is a full size dump truck worth of material. 

Is there a combination of lending products and tactics you see that can make it possible to refinance after possibly 2 years and get out a large enough portion of funds to use towards the downpayment on another property?

After that length of time I felt my Ex deserved a portion of what had been accumulated.

How about a modest salary during the hold period for the capital raiser, no big acquisition fees, disposition fees, or AUM fees/management fees that scale with size, a requirement to be full-time on the job managing the money, and large upside AFTER LP capital has been returned?

@Andrew Caton What size deal are you looking for right now?
