Scaling our Airbnb/Vacation/Short Term Rental business/portfolio

[Alex C.]

My partner and I have been investing in short term rentals, for 3 years and, now have 14 properties we operate full time in the Los Angeles market. Through trial and error and putting in the work we have developed systems and strategies to grow this business with no outside investment. We've hit a ceiling and would like to scale up because we see the demand is insatiable in the LA area. We are adding a unit or two monthly by reinvesting our profits but still have more deals being presented to us because of our branding and track record. 

Any suggestions how to secure additional capital in order to grow our portfolio even more? We are looking for about 25k - 50k. We don't own any of the units but have arrangements with owners/property managers which allow us to operate by sharing part of the revenue. We are consistently generating 150% annual ROI and have done over 1000 transactions on the Airbnb platform. Any feedback would be appreciated.
