IE once you go down the road of buying rentals and if you ever want to ACTUALLY exit without giving the portfolio to your kids or charity you have recapture.. so you can end up getting on the Hamster wheel. you end up having to stay in the asset class for fear of a huge tax payment.Now that all said diversification is something to look at maybe you spread your funds around to a few different investments don't put them all in one spot. 

I wouldn't rush to pay off anything under 4%, as this is almost free money.if you have high monthly loan payments, relative to your monthly salary you may have trouble finding financing. if your loan payments are lower it may have no effect.remember, this is all a  numbers game. if someone says you always have to pay loans off, that is because they are risk averse and let fear talk. rational investors make decisions based on numbers and facts, not fear and emotion.

I am new to real estate investing, but now new to Bigger Pockets; however, I did just find my way out of my "hole of fear" and decided to get back into learning and doing. 

It just takes some effort to learn how to fine-tune your channels and determine what is noise, what is irrational fear, what is solid ground.

Of course I have fears, mainly, what if I can't find renters. 

If you fear for your safety contact the authorities. 

I have missed opportunities just because I feared calling.

I let them know that these are your own personal  goals, there is no cheating and copying others goals, unless their numbers seem realistic.It's up to the individual and what they want out of this real estate investing.Remember people your goals can change, just because you set your target high or too low, as you progress, this can change, nothing is set in stone.for myself we set our target low at first but that was 2 years ago and since then our path has changed and our target is now heading in another direction.but  no fear, we just keep pushing on to get more deals and looking to do larger deals with a JV or limited partners. details to follow.eg. years ago i had a target of owning $10,000,000 worth of real estate, and hoped it cash flowed in the $7000/ month.but changed the plan to now target for owning $100,000,000 worth of real estate and having a monthly cashflow of $15,000/ month minimum.what are your targets in this world and are your targets too high?

@Hector Gonzales Do you mean that you fear your debt to income ratio will be too high or that in actuality, you will not be able to afford and pay your portion of the monthly payments?

Your tenant is on a month to month lease so you can rewrite a new lease at any time and require them to sign and abide by the lease or if they refuse you can give them a 30 day notice that you are terminating the lease and they must move.You are not in a precarious situation and it is very easy to fix everything without a lot of fear or work.1.
