You will have income (rent), but then you'll have expenses: taxes, insurance, repairs, turnaround cleanup, eviction/attorney costs, vacancy factor etc.

First, don't use REI Reply, it's just a white-labelled/private-agency version of GoHighLevel (the actual provider of the CRM) that they just mark up and charge you extra for everything you do (every text, email, etc is 2-10x more expensive than just linking twilio/mailgun to your GHL account, etc).With that out of the way, you can get to making workflows.

In 2016 the pittsburgh market is getting too darn expensive in the hot areas (especially east end).  

We’re planning to move to Europe to start our family, and we’re looking to generate $1,000–$2,000 USD/month in net income (after management fees and other expenses) with these RE investments.

In many urban situations, one of the trenchless technologies will be less expensive than dig and replace pipe renewal.

For example, a $650k 3-4 unit where each can rent out at $1,500, allowing for a negative cash flow of $2-2.5k/month the first year.PossibilitiesGiven those goals, it would rule out the more expensive places (California, Seattle area, Austin).

This is because they didn’t budget properly and rent wasn’t high enough to cover actual expenses (repairs and maintenance, cap ex, vacancy and loss, tenant damage and turnovers, etc don’t expect to have any money left over after all of these expenses are accounted for if the rent is less than $1,500/month). 

Once all of that is figured into place, I look at the expenses of the property.

If this were my deal the sale price on a triplex would likely be around $900k, so if I bought the land for $150k, and my build costs were about $500k, I would expect my interest and carrying costs to be about 10-12% of the total of that, so lets say $75k, for all in expenses of about $725k. 

As you know property is expensive and you don't have a business running that generates revenue.
