In the beginning you might be cheaper but will have growing pains as you expand and will not be able to scale and maintain that little profit margin model.Personally I think many buyers overpay for investment properties and then blame the PM when they did not properly account for that expense going in.

 @Eric Fernwood:I definitely agree, this sounds like it require a proper cpa/lawyer opinion.

Sounds fishy and sounds like they don't have proper documentation for what you are claiming.

I have seen a few rookie investors hiring people that say they have experience and the next thing you know, they paid for a roof that now needs to be removed and replaced because it wasn't installed properly.

That leaves:1) Taxes: is the property properly assessed? 

Also, from a SEO perspective, as you optimize your site for just that specific function and add gobs of content you will see an improvement in search rankings.Here's another way to look at it - let's say you need a plumber and you have the option of calling a plumber or a GC.  

So he won't have proper landlord references.. 

Something I need to conduct proper due diligence on and run by my RE attorney possibly.

Some tenants actually use the transfer function with their bank as well. 

So properly reflect on your conduct as some things have unintended consequences.
