Most regular rentals that I have come across are not furnished.

If the truck is beneficial to you (you use it to haul/tow on a regular basis) - I'd say the cost is justified and you should keep it.

On the flip side, if you need to exercise a lot of control over your investment to be comfortable (ie. be able to see the property regularly, choose tenants yourself etc) and you'd rather have control than free time, then more passive buy-and-hold options may not work for you.

Cell phones, rent, credit cards(get secured if you can't get regular), store cards, gas cards(those seem harder to get for some reason).  

When cash buyers call, tell them it's been sold, but you always get new deals on a regular basis, and you can add them to your cash buyer's list.

I do this on a regular bases.

These are 2 REI clubs that meet regularly and have been around for a while.  

The weather can play havoc on your property in cold winter areas.You need to make sure the property has been winterized by having the heating,water heater,pipes,rain gutters,and the like are serviced for winter and fully inspected.Make sure you have a snow removal plan in place like the tenant has to do it or you pay someone to do it on a regular basis.

We both think that starting a group who meets regularly to discuss South Austin, Buda, Kyle and San Marcos would be beneficial to everyone involved and lead to great connections in the area.  

We agree with @Jonathan G. about keeping filters changed regularly.
