New to portfolio lending - could someone help evaluate?

[Manuel Savorelli]

Hello board,

as the title of the post states, I've new to portfolio lending and I was trying to evaluate an offer that I was recently approached with.  

The lender is willing to finance in an equal amount to what the property can rent for, up to 80% of the purchase price.  It can be for a single property/condo, or lumped up for up to 10 properties.   The interest is 6.25% and can't be used for flips, as they charge a pre-payment penalty if you pay off the loan within the first 3 years.  They don't look at tax returns or debt to income ratio to qualify -- basically, good credit and whether the property is rentable/numbers make sense.

Any thoughts, suggestions, criticisms would be greatly appreciated.

TIA,

Manuel
