You can try to play the game of hoping for short-term appreciation between when you buy and sell and this could work for a while, but at some point prices will either stabilize or drop and you’ll be left holding a bag of properties you can’t get out of.

Bag the ends.

I'm currently in the middle of purchasing an apartment have met with the seller to discuss the real world numbers revealed during my due diligence.The seller has been sold a bag of hope from his broker and today, it was necessary to present the real world numbers and the impact it has on the selling price.

Well commissions are sort of a mixed bag, with a lower fee sometimes agents are less likely to want to show the property and they will snub you. 

Easier bets are get a newer property - out of state - where property taxes are < 1 % , HOA below $50, no special city taxes, good schools and high median income of residents - if you want to obviously buy in class A neighborhoods and be a passive investor and bag a cash flow of $200-$300 per month with a chance of appreciation in next 5-10 years.

As wholesaling is not my cup of tea. 

Lock in a lease but pack up your bags at a moments notice.

If you are 'wholesaling' because you have no money, start brewing your own coffee, brown bagging lunches, avoid car payments and work more!  

An ocean of garbage,6 dead rats later and currently up to 90-contractor sized garbage bags I've hauled out of JUST this room (really wishing I had remembered to take pics from the start, as some of the piles of garbage were towering way over me). 

In general,  you get more bang for your buck if you can read the gentrification tea leaves and get into theos neighborhoods.
