The more complicated your business structure becomes, the more problems it can actually cause such as when looking for lending options, getting the best interest rate, keeping clean accounting, filing taxes, opening bank accounts, getting credit cards, executing a 1031, making title insurance claims or even triggering a due on sale clause, etc. 

@Natasha Rooney rates will also be different depending on if you have Credit or not.

My current credit score is ~770 4.  

If all of the equipment for fully automated remote supervised tours was acquired on a credit line, I think you still have a problem with all of the different logins one one device.I'll let you know what I come up with.  

To qualify for debt, lenders generally look at net worth (aim for the loan amount), liquidity (10% post-close), experience, and a solid credit score (ideally 680+).

I do a rent by room strategy, and I use a tenant application platform (Turbo Tenant which I love) but they're having trouble inputting their info....Is there another way to verify income, credit score etc with a foreign visa?

We allow Tenant Portal (ACH), Direct Deposit to our bank, Venmo, Strip (credit & debit cards) and old-fashioned mailing of checks. 

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.

A person who has 26% credit card debt, a 8% HELOC or credit line can use even small amounts of excess cash to earn money.

this is old  tried and true method of simply having you pay them to get credit cards .. there is no need to pay for this service.. unless you want to of course.. there is no magic bullet ut there that is going to give you credit and financing unless you actually qualify for it.But zero interest credit cards are used by some to do rehab and then pay them off issue is though your fico score drops like a rock the second you take on all these CC.Also starting out there is zero chance of getting any kind of business line of Credit that is unsecured.
