While I agree the rent by the room strategy can be great if you know how to manage it well, from a lending perspective, a lot of 30 year DSCR note buyers won't allow properties with individual room leases, so it could make refinancing more challenging. 

I've seen rental units get leased with iPhone photos that have good lighting. 

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

I agree with Jaycee, but be cautious with other organizations having a "master lease" on your property.

However, I still have LTR tenants whose lease will be ending soon.

This could be a great way to get started as you'll be at the property everyday and by living in the property not only will you be there firsthand to oversee the work being done, but you may also find new potential issues while living there.If you're looking to do this, I'd recommend a 203k loan to purchase the property and get some rehab funds. you'll just need to live in the property for a year before being able to lease it out to a tenant.

1) I always use zillow to list new properties and use there platform to accept zillow applications2) Doorloop for management that includes accounting, repository for documents like leases, collect rents, tenant communications3) Received lease agreement from a lawyer

I run into this issue frequently where NJ investors are looking into out of state thinking it is cheaper, that's not always the case. 

My name is Jed Butikofer and I am currently located just outside Bakersfield, CA, but move frequently for work. 

We are now at 100% occupancy in our apartments and our restaurant is committed to a 3 year NNN lease and a $150,000 renovation at their own expense.
