Since it's a vacation rental, I am able to improve it in between bookings. 

Being open for feedback is what helps investors (everyone really) learn and improve.

If you attend local investor group meetings you'll be able to find investors that have the funds or access to the funds.

A $300K property will have “improvements” to depreciate and he will have mortgage interest.

I wish I could close up shop and be full time RE now, but I have to be an adult about it and will likely do both for 18-24 months before my commissions can sustain my life and investing.As for brokerage, since I started and built my own successful business, which I still currently run, I needed a brokerage that offered good educational access and support, but also the freedom to set my own schedule. 

I ended up taking out the equity so that I wouldn't lose access, and have ways of offsetting the interest and look at it like an insurance cost.

@Adriel Hsu that 57% expense ratio is high too and sounds like it gives you some room to improve NOI.

But with us doing 2-3 remodels a year at a minimum (and this doesn't include the smaller jobs, such as finishing attics and improvement projects on the rentals, which we also do year-round), and having 11 full time rentals, in which the employees take care of, does this make sense? 

The LTV is calculated by dividing the loan amount of the construction-to permanent financing by the as-completed appraised value of the property (the lot and improvements).

I say this because most people use a realtor to buy and sell SFH/4Units but a large part of the rental market is done without using realtors, which in turn makes the MLS obsolete as far as rent comps go in my opinion, but definitely still check it if you have access.
