@Robert Howard, I'm not impressed by your Agent if they failed to mention to you that relying on "tax assess value" is a BAD idea! 

Portfolio loans do vary widely - from higher interest rates to shorter amortization schedules - so make sure you know all the details BEFORE putting in a contract on a home.  

However the amount will generally vary with financing and/or location.

So I am hoping to rely on my previous knowledge of construction and having rehab'd some previous homes of my own to enter the investment market and flip a few properties to hopefully expand to buy/hold. 

My maximum loan is about 1/3 of balance with a max of 50k, but plans vary, so you'll need to check.If your 401k is with a previous employer, you'll be able to transfer the entire balance (or partial) into a self directed IRA to use for REI.Hope this helps!

@Joe Splitrock Exactly, I also spend a few hours and verify the #'s and have found some errors like a couple things mistakenly omitted, that's one thing, but putting out a wrong date in an email to all your clients who will rely on it is quite another.  

But I would check to make sure she personally has employment that covers the 3x's income/ rent, is she going to be relying on child support or spousal support that may or not get paid to make the rent?

I wouldn't rely on the tool you reference above.

I would not rely on being told something was "new".    

Of course, I do not solely rely on the tenant and am not shy about a thorough inspection.
