Mortgage payments, utilities, service contracts, etc.Similar, the tenants should not be paying to you directly but pay to the accounts.  

And my wife for the support.The best part of it all is we just found out we’re having a baby girl early next year and we added $100 automated principal payment each month to our 30yr fixed mortgage so that it amortizes when she turns 18 as @brandonturner suggests.I’m so grateful for bIggerpockets and the community it’s formed to inspire and support me through this journey.Next year I hope to do my first BRRR!

Is 0.75 multiply against what is charged for rent for the month or is multiply to the cash flow I get after I subtract all expenses such as insurance, taxes, and paying the existing home mortgage?

Who has huge network and would be able to recommend mortgage brokers, appraisers, real estate attorneys, etc.Are there  any other certain criteria we should look for?

We are new to real estate investing and have heard it's difficult to obtain a mortgage under an LLC name.

Seller financing would require them to be able to have enough to pay off the mortgage that they are delinquent to their mortgage holder, and then accept payments from you on the property.

This is really no different from any mortgage or hard money loan.

Iam getting into rental property and for my first house should I put my profits toward the mortgage to get it paid down quicker?

Albeit there maybe a few that are willing to I am on board with @Joe Villeneuve why not do a mortgage?  

If there was an old mortgage (unlikely on a lot) then you need a release from them.I have done this multiple times and not needed an expensive Quiet Title.
