Question on buying from a wholesaler

[Joseph Leonard]

BG Community,

I'm exploring options of purchasing a fix and flip through a wholesaler. I'm a newbie and have not done this yet. My question is, do wholesalers typically allow you to see a home before you make an offer? To me I would think this would be a no brainer that they would, but just am not sure on this. 

If no, any tips on how you can estimate repair costs? Some rehab costs I understand you can estimate from pictures but what about seeing the layout of a home to determine if you're going to need to knock down a wall and say rearrange a space? Thanks for any help anyone can provide.
