I would say you have a screening issue of your first batch of tenants had to be evicted.

They batch the deposits together and you have to go deep into the program to determine which tenant made the payment, that was deposited into your account.

I often buy several water heaters or large batches of shingles when they are on sale knowing I will use them within a year or 2. 

Maybe I need a new batch of buyers.

while still trying to keep up with the competition Do you rely more on direct-to-seller marketing, networking with agents, leveraging platforms like PropStream and Batch Leads, or just by looking at a lot of deals?

Find your cash buyers via propstream, batch leads etc.

Large investment groups and small investment groups have been scooping them up in batches over the last ten years. 

Batch is good for built in ad ons.I’ve come to realize neither program is going to be perfect.

There are rotations that happen every year, where soldiers leave for the next station and then the next batch comes in soon after.

I've tried a couple - truepeoplesearch, white-ages, property radar, leadsherpa, batch leads...Some services are better than others, but it is a numbers game and you also can cross check between different platforms.
