Many exaggerate their successes to get you to invest with them.

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.

Borrowing against your paid off house without an income puts way too much pressure on the success of whatever deal/project you decide to pursue. 

Hey Surya,Welcome to the community.Wishing you success on your journey.

I am perfectly fine holding X amount in real estate.If I do see an opportunity another option is to lock it up and sell one of my existing if I think this property will perform or appreciate significantly more.

What is the reason that you are not having success?

@Chris Kay finding a quality, cost-effective contractor is extremely difficult:(There are thousands of contractors that are great talkers, but rarely perform within budget.Standard bait & switch is to lowball a bid, then once they get started all sorts of things "pop up" that somehow their bid didn't cover.

It reminds me of the Charles Schwab study - their best performing retail investment accounts were from dead people that never closed out the account.

How do other regular condos perform versus them? 

Alternatively if they all love the deal, that's also likely a good sign.You can get a dog of a property in a crap neighborhood that will yield a 13.6% gross cap (not saying yours is), but that certainly doesn't tell the whole financial picture of how the asset will perform.
