I have enough in savings to pay for it but I keep asking myself should i just sell it and get it off my plate and lose the low interest rate or bite the bullet and do a big rehab and continue renting it out.

@Robin Simon im afraid im losing out on potential equity on my property with another product that is not IO.

this is a great way to lose money and there are endless examples on BP of folks in HCOL areas who have done this and regret it.in a couple years maybe you can keep your condo and rent it out if you're under the cap. 

However, its highly unlikely that an owner will keep a dog property, that loses money, constantly requires repairs for 37 years. 

DSCR is high risk NON/QM so it puts a lot of emphasis on Credit scores 700+ and the DSCR ratio 1.00+.

Because then you would lose your expertise of yours.The cost, is always manageable when you yourself as the manager of the house. 

On your last quote, I often tell people there are properties that they could get for free that they would lose money on. 

I know in other markets I have set up financing for wholesalers be it 7 days  or 30 days etc allowing them to actually close so they are not risking losing thier deals and all the money and time they put into getting them.  

You are losing up to 3% on each investment property purchase, also, you get a lot of great tools for evaluating properties, market research, etc.

If I need to spend 6 months on this I am losing 20K almost for nothing.
