Are you living a lifestyle that allows you to save money aggressively?

Charge high rent to weed out the low-lifes, Etc.....I'm sure you already have this in mind.I would just hate for your first STR guest walk in and feel/smell the college lifestyle ambiance.

For someone seeking to retire, exchanging into more properties may not be congruent with the lifestyle you are seeking. 

I've seen many say they will and then realize its not conducive to their lifestyle or commitment level.Are you making offers?

If not you’ll probably be lucky to live a Lower middle class life style.

With the move, you may need to coach your parents into a lifestyle that doesn't require the luxuries of the city.

Amy, most investors go through this twilight zone of how to work a job and juggle landlording before your portfolio reaches critical mass (enough net positive to sustain your lifestyle).Ask yourself what are the greatest challenges you have with your properties:  Rent collection? 

I have a high paying W2 so I don't use any of my cash flow to pay bills or support my lifestyle.

@Jake Stuttgen thanks for the advice.At this point it would be payed of monthly by my other properties with out affecting my lifestyle saving or any other day to day.
