Real estate investmnets are capital intensive and if you don't have extra money sitting around to make the emergency repair when it happens you'll find yourself in a terrible position. 

or just explain as in a demand.it this 40k gross or Net.average rentals these days produce either negative cash flow or 100 to 200 to 500 a month positive depends on how much you put down. if you pay cash much higher.but lets do average 200 month positive and lets say you meant to ask NET cash flow to live on. then you need to take 40k divide by 200.00 and there you go you need 200 doors .

I'm looking to finance the project long term in a way that is helps me create positive cashflow.

It sounds like you’re in a great position to succeed, given your extensive renovation expertise.As a fellow real estate investor, I completely understand how challenging it can be to choose the right design elements, especially when you want to make a space appealing to potential buyers.

These properties are generally in high demand, but on a positive there will be drastically less new inventory of competing rental properties. 

If it's not positively cash flowing, it's not an asset. so what's the point of holding it?

I recently did one where the lender did allow it but that was because of our position as a great customer of the bank and our impeccable credit record.  

Left me feeling like a basically have a retail/fulfillment person on my team so I'm a big fan and would recommend giving them a shot, especially if you're in a similar position as I was: Needing to furnish an STR quickly and cost-efficiently. 

Either way, sounds like you’re in a good position.

Look for the positive in all situations.
