You just need to work with the lender and show that you can afford a down payment and the monthly payments. 

I have a tenant moving out at the end of the month and the tub needs some TLC.

That may only be $6-12k/monthly income in 15-20 years. 

It is much better to add a reserve fund to it monthly.

I went live for my airbnb in March and have seen a significant drop in bookings since this month.

Doorknocking is also very effective but difficult in the winter months.

If not, and although I'm not a fan of this, can someone spot you a couple grand for a few months so you can get it down?

I have started to make offers on some deals in Columbus, hopefully should be able to close on one within the next 2-3 months if not sooner.

"Most" water damage claims can be fixed and closed within a few weeks or months, where a fire claim "may" take 6 months to 1 year to close out due to more extensive construction, delays in materials or labor, weather/seasonal delays, etc. 

it's very difficult to cash flow in month 1, or even year 1.
