They are NOT underwritten with an eye to being sold to the secondary mortgage market and they generally stay on the books of the banks that make the loan.A word of caution, though:  all loan types except HML look primary at the credit-worthiness of the borrower and secondarily at the asset. 

Finally, insist that your property manager place a credit-worthy tenant where the rent requires 3x the amount in monthly income.I’m not a fan of the term “Passive Income”.

@Aaron XieAlso you need to remember that the more stable/credit worthy the tenant is, the generally lower cap it is.  

Some list sources (I'm sorry, but I don't recall where I saw this) will let you search on various factors, including credit worthiness. 

Since you bring up DTI, I assume you are not talking to a commercial portfolio lender although I can't know for sure as they could be evaluating your creditworthiness as a guarantor.  

,I hear of smaller banks with no PMI on less than 20% down.and my other light at the end of the tunnel was a 3% down multi family qualifying loan with no PMI if you are 720 FICO and 3 month reserves in bank.i I am now credit worthy (mortgage score qualified) and after selling my wife on the fact that our 2016 tax return ($7,000) must all go towards our first Investment property and first property in general as downpayment/reserves.

Learning that discipline will allow her to become credit worthy.

I'm reasonable successful at looking for/analyzing deals, cash and creditworthiness to finance them, wife is great at designing the remodel/build.

Like Elizabeth Colegrove said, if you are credit-worthy, qualifying for the first loan is relatively easy.

Improved credit worthiness will improve the whole deal and offer greater options.Jon gave some pretty good details. thanks for taking the time on that Jon.
