Will that full 20k balance be due the following month like a credit card? 

My capital and credit. 

I have had really good luck with Utah community credit union.

I'm told I should be looking at credit unions.

After working with Navy federal credit union, I was able to get approved for ~600k(1-2 unit SFR), 30yr foxed,4.5%interest, 0%down, and 2.2% VA funding fee which is wrapped into the loan. 

nice post.. were i see 100% financing is for EXTREMELY experienced operators that have been with their HML for years and years.. and the deals are no more than 60 to 65% LTV.. this does happen.. but its only for those special few repeat clients that have years of working experience with the lender. totally agree on the ones that require a larger fee up front I just hearken on the American Greed episode with Remmington Financial the King of pump and dump due diligence lenders.. 

During that time I’d also have the line of credit to pull on for repairs/vacancy/maintenance, and I’d have that line already established for my next investment.The second option is to put traditional mortgages on them in 6 months once the sale seasons.

Local banks will work with you if you have stellar credit and a good track record.

I am the real estate agent and we used James Hirbour from Jeanne D'Arc Credit Union for the mortgage and had a great experience.

Sure you can cheap out and go with the craigslist special and maybe for some jobs that's ok or makes sense.
