If one genuinely plans to hold the loan without selling or refinancing for the full term, then rate should carry more weight, but even then, a few extra payments to principal easily offset a higher rate.I've had at least 5 investors this past few weeks show me offers for 4.5-5% rates on some of the worst loan terms I've ever seen.  

I said no problem, you pay me a portion of that rent every month you are unable to uphold the agreement, and no rush, we can do this forever. 3 months later we were able to close with a price reduction of that rent.If I was purchasing your property as investment income, and the seller is delinquent, I would notify everyone involved that I will be taking action.

Major rent price reduction?

Also, is this reduction in available credit the result of the mortgage rates going up and what I can expect from most brokers at this time?

$12k rental income+6k reduction in money owed+home price increase/300k equity?

Asked for 20k on price reduction in lieu of evictions.

if you believe a recession is coming, it is prudent to plan for occupancy reductions   Good luck

I'm seeing substantial price reductions on some types of properties/some areas in London, albeit from a high base.

If that's the case, i would suggest you stop with price reductions and begin offering seller credits instead. 

It was expected to end in 2021, however as part of the Inflation Reduction Act, the credit has been extended through 2032.
