Thank you all for the great reading and research material- I never would have found this home or a lender willing to work with me and my bad credit without it!

My question is when we go to get a mortgage, will a appraisal for a traditional mortgage give any credit for the warehouse or will it just consider the value of the house?

Read this in "Landlording" by Leigh Robinson:  

Lines of credit on your home or other rental property are another option not yet mentioned.

The membership also gives you discounted tenant screening services (credit score) and they offer a landlord training course called Rent it Right.  

Have great credit and have the money to put 20% down but what's the challenge in that.  

I would begin talking to a lot of your local banks and credit unions to see what they will allow.

When you refinanced the following year, did you run into any issues with having debt from your HELOC on your credit report?

My question is: if we redeem our personal credit card points for Lowe’s / home dept gift cards to go towards supplies/materials/cabinets etc, can we deduct that as an expense even though we used a gift card vs a credit card or cash?

That means you need to know what kind of financing you can get and what the terms will be. many investors hear about homeowner terms and thin they can get that because they have good credit.
