Friends, family, even people I found from posting ads on CL have enabled me to continue to accumulate more properties...which are income streams.

Hold onto the property and continue renting?

Just like you shouldn't continue with closing if you discover a huge leak in the roof, you need to delay this closing until the tenant is out.

You also pay annual fees, attend continued education classes, etc.I would caution you however, that you should instead offer a different approach.

Smaller flips, time in and out in 1-2 months, will be more profitable over time and allow you to keep quality contractors continuously employed.Spending more on hiring more contractors will effect bottom line on one flip but enables you to do more flips in same time period increasing over all profits.

I personally like a mix and will probably continue to buy a mix of turnkey and non turnkey in the future.The turnkey provider I use also manages houses I don’t buy through them.

So while a Fannie/Freddie loan will be a 30 year fixed rate that is pretty low...a portfolio loan might be an Adjustable Rate (which will make your payment change), or only a 15 year term (which will make your payment higher), or have a higher rate all together...and I have seen many a portfolio loan that has all 3 of those features. 

Just make sure to make smart bets and continue to learn as much as you can.

Not sure if it's a peak we are in, but I'll continue to sell a couple houses a year as they turn. 

Continue to read as many blogs, books and articles as you can in order to educate yourself on the topic and to reach out to those that are doing what you want to do!
