Joe,I really hope you get some good responses here with how specific portfolios have performed over time.I can tell you that the type of property you purchase, the location of the property, the amount of rent paid by the resident and probably most importantly, the quality and level of renovation are going to have a major impact on performance over time.   

Maybe the houses are worth a good amount and maybe you only would consider selling them in a package deal later. 

Please click on the links, give them a read, and share your thoughts in the comments.First is a post that I feel will help not get overwhelmed with the amount of info that is here on BP:https://www.biggerpockets.com/blogs/5868/52761-the-simple-guide-to-getting-started-on-bpThe second is a post that will help get you focused with your real estate investing goals:https://www.biggerpockets.com/blogs/5868/52743-im-new-to-bp-any-advice-would-be-appriciatedThe last one is a post that will help you choose an “investor friendly” real estate agent.

If the house appraises for 'X' amount from sales comps, Will would not be valued for 'X' + 15k of structural rehab above that.A real appraisal is just $400-500.

The amount of information out there is overwhelming, and yes, when I’m reading those “best places to invest” type pieces, I figure hmm, well I’m not the only one reading this so it’s probably too late in this or that market.

This is my (50-units) portfolio data in Las Vegas:Total contributed capital a few years ago:  $572,000Total loan amount:  $3,078,000 (I have been cash-out refinance many many times to pull out more equity.)The four townhouses I just purchased in Feb 2018, the down payment came from my another cash-out refinance.  

Agent's make a relatively large commission because handling all the headaches of the two competing parties during an escrow oftentimes amounts to a full time job, especially with a cash sale where everything usually moves very quickly.Good luck with your deal!

@Namit Raisurana, on the surface of it, are you sure you need to concern yourself over $3,500 (0.7%), when it'll get you double the amount you'd get otherwise?

That being said...it can take A LOT of time to process and dig into.The amount of info out there can be about all sorts of investing niches and opportunities...it can be overwhelming if you don't have your end goal in mind.Have your end goal in mind...what do you want real estate to do for you? 

And even then, as you suggested, you need to save up (or reserve) a certain amount each month for future CapEx.
