You would need to apply that same methodolgy to a recent duplex comp to get a usable multiplier that is applicable today.

As a Loudoun County Realtor, I echo everything @Heather Skowronsky says: short sale doesn't seem applicable here, and your parent should be able to sell it to you for whatever they like.Your issue with this potential purchase may be having enough cash to close. $20k for a $450k purchase gives you <5% down, and doesn't consider closing costs. 

And one about how I was always pushing the 1% rule which was easy to shut down by pointing to all my posts about how it wasn’t applicable in my markets and it didn’t make sense since it didn’t consider tax/insurance/maintenance/price/property age differences. 

There are several that specialize in East Side apartments, you'll see their names on Zillow and Craigslist ads for the area but if you can't find them for some reason I can give you a couple to call.Usually in RI it's the landlord who pays the rental agent fee, so it shouldn't cost you much of anything (maybe the price of a credit check or small application fee) to use a rental agent, if you choose to do that.Good luck and if you have more specific questions feel free to post them here too :)

I'm new to the board and I apologize if this topic has been discussed numerous times before. 

I could see it being a consideration given two equally strong applicants, however.

It has been listed about a month and I get a lot of initial interest but not many qualified applications.

HI all, If you have tenants who fell behind on rent payments, City of Philadelphia just released an emergency assistance program that will accept application only between May 12 and May 16th.

They said if you own more than THREE rentals they will not accept a mortgage application on a primary residence.

It all started with rich dad poor dad, since then I’ve consumed numerous hours of BiggerPockets Podcast & Get Rich Education.
