@Ken Yeung I would definetly look at what rental rates are for your home, make sure you compare apples to apples if it is a 3/1 or 3/2 etc. 

I'm not a mortgage broker, nor do I play one on TV - search the forums for previous threads on VA loan and see if anybody's name continually pops up with useful advice then reach out to them.Continuing my assumptions, let's say you find a duplex in your area for $300k. 

Like Stuart pointed out, you want someone to partner with or work for that will turn into a mentor, not someone that is "mentoring" nationwide because they had a hit TV show.

November through March is typically a little lower.Also need to compare apples to apples and make adjustments appropriately. 

A property leased to Apple for 30 years will command a much higher price than a multi-tenant office building with similar rents.

If you are planning to pay back HELOC within 2 years, lets assume you would need 130k for down payment to do the apple to apple comparison and plan to pay back in 2 years. 

I actually just replaced an "espresso" shelf in my tv stand with a generic piece of shelving.

If you're comparing apples to apples when trying to decide then, sure, the higher return is the obvious choice.

This is the only way that you can truly get an "apples to apples" comp for any house.
