IO, 30-year fixed and ARMs all available.

Some investors choose i/o periods because their cash flow maybe negative and it makes senses in their books to pay I/o for 10 years let’s say.

To answer your question, 5-7% rates, 100% of rents count towards income (ratio is gross rents/PITIA needs to be more than 1.00, and there are lenders who can go less than 1.00), my clients like the 40 Year I/O (10 I/O, 30 year fixed, locked in NOW).

We are getting quoted 3.99% for residential and commercial with only .5% on the points and 25% down on purchase and 20% down on reno with IO period if needed. 

ARM loans at fully indexed no IO or start rate.If $6800 is long term market rents total and appraiser verifies. $950000. sales price PITI with 20% down $6600 PITI covers and leaves wiggle room with no HOA.In general 20% down does not cash flow in most markets.

On my phone, I use the native scanning integrations on the Files app on iOS.

A few years ago most deals I saw were underwritten with maybe 6 months of I/O while on a bridge loan before locking in permanent debt.

Are you sure you're at 5% on an I/O? 

I have 2 currently, both with 2 different credit unions, and both were no-brainers on low (no) closing costs and lowest rates (still 2.99%-3.99% IO HELOC with 10-yr draw period and 15-yr term).

Fortunately, we were able to stabilize our clients' 12-month hard money loan that had a balloon payment at end of the term with a 12% I/O payment.
