Have any of you encountered that experience before?

By obtaining multiple financed properties you could be using up a few of your slots out of the 10 available under your name.Commercial banks can do blanket notes which have less favorable terms (3, 5, 7, 10 yr balloon usually) and rates will be a bit higher typically than conventional.A lender who packages all mortgages together in one transaction could underwrite and order docs on all files at once (3 set of docs, 3 mtg notes, 3 trust deeds etc) for signing so could be very streamlined.If These properties are to be held for income producing purposes the least expensive money with the most solid 30 year fixed terms with be conventional financing, but even with conventional there are pros and cons.

I had never encountered this and it’s thrown me off.  

Most states require HOA resale disclosures during sale with a right to exit contract within x days' review of resale disclosure package, so if you don't like the rules or fees, you can exit the contract without penalty. 

I was never aware that I should look at the thickness of walls during a walk through; it isn't something I've ever encountered or expect to encounter again.

The reason being, you will encounter many obstacles on the way to success.

Plus, a tenant who are living in the house and who  at the same time  are working on the house, what kind of problems Could I encounter?

Fast forward to the tail-end of my second deployment and I'm finally debt free, saving up enough to have rehab funds to accompany my VA loan for the first property.Where did you encounter the most friction when you started off?

I also think about my exit strategy and will I encounter similar issues when I'd want to sell (having difficulties selling because of property issues).

The only problem I've encountered is that lenders are not familiar with the the figure that Form 2555 generates and drops into your 1040 because its listed as a credit - currently $103,900.
