Been speaking to realtors but just looking for solid online resources I can also utilize. 

A cash out refinance is based on LTV, has seasoning requirements, and would be subject to higher rates. 

The barrier is the additional complexity - now you are operating two sets of books, and filing two tax returns, and have more operating agreements, more state registrations, etc, need to manage cash better, need to keep in constant mind that your rents need to be a supportable FMV, which may require getting third party certification on your rents so that in the event of an IRS audit, what you have done is supported.In short...the size of the project, and the taxable income, need to be of enough scope to make all the additional costs and annoyances worth it. 

I've thought about it for a rental property, but it would require an internet connection, conceivably the tenant, in order to provide the feedback from the meter portion. 

Here are the numbers, so you can see what I mean.The numbers are the following: 359,900.00 sales price (purchased Dec 2015) 89,975.00 down payment (25%) 10,000.00 closing cost (estimate - I don’t remember the exact figure) 7,000.00 required rehab (estimate - I don’t remember the exact figure) 106,975.00 Cash invested 3,900.00 Rental Income (actual figures) 150.00 Parking Income (actual figures) 4,050.00 Total Inflows (400.00) Utilities (250.00) repair budget (not an actual outflow, yet) (2,200.00) Mortgage (Includes insurance, taxes, and P&I) 1,200.00 Operating Inflows 14,400.00 Yearly inflow 13.46% ROI If I were to use the 50% rule I would have discarded the property. 

Rentometer and other online sites (Zillow, Redfin, etc.) are not accurate enough for evaluating specific properties.

Anyone who works remote or online or does low skill manual labor.

To be sustainably successful requires a marketing budget of $5,000 - $10,000 per month PER market area.  

This can be a great workaround because many states require a physical address for your LLC, and a PO Box won’t cut it.

Most out-of-state investors will have an enormously difficult time navigating that process from afar, especially in a market like Detroit.We help folks with it but our projects generally require investors to be cash buyers.
