How do you suggest enlarging my portfolio after I start if I'm focused on paying the property down?

Nearly the entire house is wallpapered so it will be nice to start everything fresh.2) Instead of just enlarging the 1/2 bath to make it into a full, we have enlarged both bathrooms in order to fit larger vanities in each.

The 25% "vacancy" is used to offset maintenance, fees, and vacancy.However, you cannot use the rental income from the vacating property unless it's 100 miles away minimum, or other exceptions (enlarging family size, employer-forced move, etc.) so your income would have to cover your vacating property plus the new property (minus 75% of the rented units.)

I've listened to tons of BP podcasts in the last few weeks, probably 40+ hours while I walk my dog each day :) And I've pored over the Beginner's Guide as well as several books in @Brandon Turner's recommended list - "Long Distance Real Estate Investing" by @David Greene is probably my favorite.
