Keeping everyone aligned—lenders, inspectors, attorneys—prevents bottlenecks that could derail the timeline.Lastly, tackling big tasks early (like ordering inspections or raising equity) is a game-changer.

Buying in a quality area and being thorough with your tenant screening are the best preventative measures you can take to avoid that situation from arising.

It can be a normal problem but you can prevent it with some certain measures.

The rules are designed to prevent related parties from engaging in exchanges that shift high basis property for low basis property, followed by a sale of the low basis property, effectively "cashing out" without recognizing gain.If you sell a property to a related party as part of a 1031 exchange, both you and the related party must hold the exchanged properties for at least two years following the exchange.

It is imperative that you take this action to prevent fines and legal issues.

But, they do get to eat a lot of pizza.Debt prevents you from becoming an investor. 

You can claim to be the best guy in the world at finding and analyzing deals, but when the market turns against you, and you just went all-in, even on the best relative opportunities that market had available at the time, there is nothing you can do to prevent losses, especially if your debt has a maturity date that will force your hand.Timing the market is an interesting concept. 

It also prevents you from making the #1 noobie mistake, which is buying in the hood just because it's cheap.

If you hire a PM, your financial account structure can be simpler.If you plan to continue purchasing rentals, I like some key accounts at the "management" level (income, opex, tax, owncp, reserve) and only have 1 checking account per property to prevent having 100 accounts and unnecessary complexity.

The more rehabs you do the better understanding you will have of the market for contacting work and materials.Doing a rehab every so often prevents you from being sharp with your budget.For those with limited exposure, ask others in the industry and always run your numbers based on being overbudget and overtime.
