I have heard of some quite masterful short term use of IO credit cards to fund rehabs!

@Kevin Wattenbarger I am a licensed home inspector in Western New York and use Palm-Tech on a iOS platform.

First Republic - CaliforniaFremont Bank, CaliforniaFulton BankGFA Federal Credit Union 10 yr draw, 10 yr repay, MAGranite State CU, NH 90-100%Great Lakes Credit Union Hanscom FCU, FloridaHSBC 70%, for premier clients only Horizon, Kalamazoo MichiganHuntington 75% LTV 5 yr IO product available.

It also offers options like 30/40 year amortization and I/O Interest only of needed.

I sold by owner my 2 apt buildings to 2 out of area syndicators on i/o contracts. 

I don't know about iOS products, although you can use the app called IFTTT to make the same thing happen on both platforms.

If the goal is a lower monthly payment, IO may be a slight change in payment compared to doing a standard DSCR.

With that said a fixed rate DSCR is still prevalent in today's market, with most of the ones I have personally been underwriting being I/O for the first five years, allowing investors time for their property to stabilize or capture more monthly cash flow.PRO: Property is qualified based on the income it produces instead of your personal income.

I was able to use a private money lender long term loan w/ initial IO period to lock this up for my personal portfolio.

6 self owned mortgage with 30YFRM is extremely different with 6 syndication 70%LTV 5 years IO debt based on SOFR.Can't compare between the two.
