What kind of ROI i should look at, considering project completion will be 3 years roughly?

The boiler/radiators are functioning just fine but figured this would be a good time to make the switch if need be.

If we use example above (bought the house for $40K and sold for $80K, roughly this is how it would work (excluding closing costs, paid in cash):Purchase price of property: $40,000PML to purchase the property: $50,000 at 6% APRDifference ($10,000) deposited to his account.Property sold for $80,000. $10,000 cash deposit collected from buyer.$70,000 financed as a 30 yr mortgage with 7% interest.Monthly payment to repay $50K PML in 5 years: $966.64Monthly payments collected on 30 yr loan of $70K @7%: $465.71$20,000 in the bank account after transaction closed. 

It attracts a rough tenant pool.

@Randall AlanRandy,I have roughly 1+m of funds, that includes open lines of credit.

Or, you could ask for a rate quote based on a range of credit scores and you can figure out what they'd charge you on your own.

I figured my network of people I help/work for, will help in the long run. 

I figured now would be a good time to jump in, introduce myself, and ask for advice.

There’s a lot different tenant types and I’ve spent a lot of time figuring things out.

I remember a saying someone told me a couple of decades ago that convey's to real estate investing: "If you've been sitting at the poker table for 15 minutes and you can't figure out who the patsy is, you're the patsy!"
