I'm looking to do a cash out refi on a duplex I have, but I cannot find any reviews online or much of an online presence for them.

The online gurus are the worst.

Just shop around online, look for properties similar to yours, add them to favorites and watch them to see how long it takes for them to rent.

However, if all they offer is general info, I think you can find most of it yourself in Bigger Pockets and other online sources.

First Solar has been developing most of the projects there, about 500MW, worth over $500M, so far with more coming on line soon.

I bought 1 House out right, I am refinancing for 100k. had 1 renter paying 1000. using the refinance to purchase the second property, and putting renter for 1400. it will also need 25k in repairs.

If you want to send me a DM I can send you a link to run an easy online quote

-Save for the next property but consider refinancing your current loan in the future if interest rates drop, potentially improving cash flow.

Look up the default risk by credit score, this information is readily available online. 

I've been running the numbers on different properties using a variety of online calculators for properties that I initially thought looked like there may be potential.
