How much are they typically paid? 

It feels like a slightly different comparison of the typical condo vs.

Typically will lend up to 80%, rate around 5%, 20 year term, resets after initial 5.This has been my experience.

If it is an online auction there is typically about a 5% fee that is paid by the buyer so be sure to factor that into your math.

I don't know if you have read The Book on Managing Rental Properties or not but in there @Brandon Turner tells the story of the typical landlord that manages his properties like a hobby and makes no effort to run it strictly like a business.

For those of you that do this often, do you typically go through a realtor to make contact, or have another way to reach out?

I understand the idea that if you only came out of pocket with only the downpayment vs buying the property outright, the CoC is typically better even though you have a mortgage payment.I guess where I'm a bit stumped is trying to figure out how to weigh the deal if we plan to use a HELOC for the out-of-pocket portions.So 20% down plus about $6k closing costs means $19,000 out of our HELOC.

An AC compressor that went out would not typically be the responsibility of the tenant.

An attorney should know what the courts in your area typically grant and what they don't including late fees and interest. 

So the question is this... what typically does a rehabber look for in terms of relating cost of repair to profit. this house is 50k profit... just so I know what to sell the house for and stop wasting peoples time.
