I don't necessarily need the standard features of pm software, such as rent collection, bookkeeping and maintenance requests, though that could help; but do need a clearinghouse of important information, such as leases, legal docs and other information; maintenance vendors I use; maintenance history; and some kind of tracking system, where I can record the various current projects I'm working on within the business.

Adding a 1/2 bath, new roof, central air or other typical improvements will increase the value of the property. 

I'm not sure by how much your rates are increasing but I have friends in NOLA who have seen a 2x increase per year.

The shorter the prepayment term has an impact on increasing the rate.4.

@Ezra Avery you might want to read below to understand Classes of Property/Tenants.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

In Portland for example we are not allowed to increase rent more than once in 12 months, and it must be less than 10% increase in "effective rent".

They are not a realtor and up to the standards of a realtor.

It's a tip I heard from someone which I heard increases the response rate. 

We rent to plenty of S8 applicants; I've always believed the standard of care they exude is as high if not higher than "market" applicants because they'll get kicked out of the program if they don't.

Over time, rents may increase, improving your cash flow, and you’ll gain equity and valuable experience managing tenants and property operations.
