How do you determine Market Value if there are no Comps??

[Robert Campbell]

Hi all, Very new to real estate investing but I am learning. I want to buy my first rental property but I am concerned that my asking price may be much higher then the banks assessed value when determining mortgage approval. If there are no comps in the area (4plex), how do I determine if the property is worth asking or what I am willing to pay? I hope I explained it correctly.  

Many Thanks in Advance!

Where is the property located?  Are there any duplex or triplexes in the area? 

Have you talked to a realtor in the area?
