The test I would use (if I were inclined to consider turnkey) would be to ask that I be put in touch with a former/current client who made money over some meaningful period of time using the system and was willing to be transparent om sharing the numbers with me. 

In declining his offer I would go ahead and set the expectation that you are granting him a promotional rent for this lease period only  and he should expect a rent increase at lease renewal.

The DSCR can be interest only for a period of time, often is 30 year repayment period. 

The unfortunate thing I sometimes have to explain to my client is that what they "want" in rent isn't always what the market will bare.Long term the real goal is to put tenants in place who will respect the home and remain your tenants for a long period of time.

And you have to close on the replacement property within 180 days of the date of the first sale (the first 1031 exchange that will expire).My recommendation is that when you get an offer for that first sale, negotiate as extended a closing as you can. 

Over a portfolio of homes, over a period of time, the expenses not including financing cost, will be about 50% of rents. 

Consumer spending is almost always up between those periods.

Hey Julian, As others mentioned, DSCR loans will be underwritten based off of the appraised value or cost basis (purchase price + documented rehabs) depending on seasoning period when you are looking to refi.

.- You won't extend the term back to 30 years (which is definitely part of your monthly projected savings). 

As I'm sure you know, this means the mortgage holder can call a note due and payable in full within a very short period of time upon learning that you've transferred the title to the property (their collateral on a loan) out of your personal name an into something else.
