2 part question I am now credit worthy (mortgage score qualified) and after selling my wife on the fact that our 2016 tax return must all go towards our first Investment property and first property in general.

The first is YOUR credit-worthiness and this is based on your credit history and income.  

You will be seen as very credit worthy very quickly--try to maintain that, by the way.

On the flip side Banks & Creditors do like generating revenue so those that are credit-worthy will likely always be able to cash out refinance.

There are some lead generators that are pure online tec businesses but as the online world has evolved and the BMV sourcing game has become more and more popular the lead generation cost has risen to an excessive level.If you are looking for a deal for you in your local area I would look at postcode credit worthiness and letting demand and look to market directly if I had time.

Yes, a credit inquiry would show when the lending institution checks my creditworthiness, but I don't believe the actual debt would reflect on my personal credit.

A credit score doesn't tell you enough about their credit worthiness.

if the business has some financials and good credit worthiness, then acquiring funds for another property may be doable. 2. what type of funding does your company have?

Banks look at your personal credit worthiness before even looking at LLC.

The next step would be to see how credit-worthy you are.
