Depends on how old they are - kind of hard to tell from your picture.

The tax assessment last year was based on the home's prior condition but fast forward to this year and the taxes have doubled.

Perform the same task in each app to ensure a fair comparison.Load a property with pictures and details.Market that property.See what your marketing looks like from the public's perspective.Submit a fake application to see how easy the process is.Run a credit/screening report on yourself.Enter a maintenance request, assign a vendor, and attach a fake invoice.Enter charges to the tenant's ledger.Enter recurring charges and automatic late fees.Sign documents electronically.Run owner reports.After testing a few apps, one should clearly stand out.

Historically, property values here have doubled over a 10-year span.While appreciation is steady, we’re considering whether to invest out of state for better appreciation and diversification.

Quote from @Bruce Woodruff: Silly question I guess, but when you're putting a property on the market and uploading pictures....what do you go with first? 

They come in with fancy spread sheets, break downs, proformas or cool looking power points with pictures and graphs.

I’d have a better picture by sitting down with someone at a bank, but I did a calculation online and the new loan on cashing out $130k would still be covered by the current rental payment.

If you don't like it, you can always sell later, but if you sell now, you'll be dealing with double the interest rate and you can't un-sell if if you feel regret. 

I made an offer on a double, it turns out that it's on two parcels with two separate tax cards but deeded together. 

So I snap pictures of paper receipts in the store and send it to that dedicated email.
