My biggest beef is with their inspections.  

I think that's a by-product of me being quite conservative, and prices being generally high in my area. 

Yes, money is important, and yes, a lot of money can be EARNED in real estate, but money is a by-product of the primary purpose of being in real estate. 

You have a house worth probably a hundred thousand or more and this beef is over $200? 

Enjoy the extra revenue and buy some of that Texas grass fed beef steak with a beer so you can chill.Now with the caged animals, I’m pretty sure they, along with a few of your co-Hart’s responding to your post, didn’t think it was a big deal.

HELOC payments vary by product, some are amortized and many have the payment set by the outstanding balance, mine is 1.5% of outstanding balance in monthly payment. the IDEAL way to do this would be to use the HELOC to buy the house in full, then refinance on the back end after it's rehabbed and rented. trying to go too fast often encourages people to do ANY deal rather than a GREAT deal, and they often don't make money. 

The rehab and resale/refinance are a byproduct of a prudent purchase price. 

Sadly, a lot of what you describe is a byproduct of law changes by those in Sacramento and California voters.  

And a byproduct of paying credit cards down your score will go up.

When I often see owner financing being offered I always beef up my due diligence efforts.
