Hey @Anette Tikkop as a new investor, the important things to have lined up on your end are the down payment (should be sourced & seasoned from/in your accounts, either business or personal), expect lenders to prefer a 680+ FICO score, and the loan amount should be $100k+ -- the lower the loan amount, the harder it is for financing. 

Applicant is confident that rent payment will not be an issue.Should I consider the life insurance as a qualifying income source? 

There are many sources for that cash recovery in a rental property...and that doesn't include refinancing of any kind.

Check out my personal favorite, Set For Life by @Scott Trench , or The Total Money Makeover by Dave Ramsey. 3.

Loopnet & Crexi are best used as sources for contacts & initial relationships with brokers, so you can build a list of broker names on those sites and go from there!

@Franko Shenault   Skeleton Key Home Inspections is a favorite of my Kenosha clients.  

It allows you to track all your accounts in one place but in regards to your comment about fees my favorite part is their Retirement Fee Analyzer which looks at your accounts and projects how much you will lose over time due to fees.

Start educating yourself ASAP.My favorite book for the last 16 years is "Every Landlord's Legal Guide" by NOLO.

"For Sale By Owner" aka FSBO leads are a common source because these are folks that are motivated to sell and are not currently working with a Realtor.Focus on speaking to as many people within a specific time block each day and do it consistently.

But then my question would be how experienced is the wholesaler you're using to source the deal?
