@Andrae S Wiggins recommend you upgrade your BP membership to Pro to access the BP Calculators to evaluate rental purchases.Play with the numbers to figure out the purchase price that gives you your target ROI.That's the number you'll need to make an offer at, NOT what the seller is asking.Yes, you will get a lot of rejects, but whoever said investing was easy?

I understand how important it is to resolve this matter promptly.I want to address your concerns regarding the delay in processing your IC Membership refund.

I am also in the engineering field (Civil and Land Survey).

You’ll need to pay MLS dues for access to MLS which in some areas requires NAR/ board of Realtors membership (~$2,000/yr in my market).
