That real whets the appetite for more.

Figure out your own appetite for risk.

Depending on your appetite for risk and need for return, will drive your decision.  

Landlords serve as convenient foils for all of those in the business of suppressing rights. 

I remember hearing 'we simply have no appetite to lend at this time' more than once. 

The thorough investor has an appetite for both, and in most cases, will use leverage to diversify across these two strategies.

I would definitely start working with other banks just in case your current bank's appetite changes.

If you don't have the cash or appetite for that then make it a 3 bedroom in the short term.

I don't want them in my portfolio so, if I can divest them to an investor with an appetite for them, I'll discount them to make them attractive to a buyer.

Hopefully your lender will make the above mentioned underwriting seamless and timely but keep in mind that every Bank and or lender may have a different risk appetite or comfort level with any given situation.Best of luck!
