It makes the whole process easier and less stressful when I have my exit strategy set.If you have to season the property before the refinance loan just make sure the interest only payments are included as part of the Holding costs in your calculations.  

With mortgage interest rates at 5% and the opportunity value of cash at 10% a so called investor is paying $2 to achieve every $1 of artificial positive cash flow.

He's a guy who spent his whole life getting/making loans, buying/selling/building high end developments and he didn't see the causes of 2008 coming.

Im really looking for something that does into detail about dealing with local government in the whole process.

I had a similar mindset as you and in trying to think through achieving the scale I wanted I realized the cash for DPs was incredible.

The collateral would be the house or should I say, the lien on the house.BUT, the whole interest rate thing sounds kinda funky.

You would need annual appreciation of about 2% to achieve that.  

He built his whole business on it and loved it. 

Then if you want, they can pay the whole rent and filing costs to stop eviction if they do it before the court date. 

None of my mortgages are over 75K and I've had zero issues and no additional costs. definitely worth doingyou should look into seasoning, almost all banks are 6 months minimum. you can use delayed financing (which I recommend) but it will only allow you to pull out the funds you put in at HUD, so you'll have to pay for rehab at the time of closing. what this does is allow you to refi as soon as a tenant is in place. the whole process for me went from ~8 months to <12 weeks.
