It would be based on the scope of work of the renovation that you're doing comparing for values in its as is condition and values after rehab 

How does it compare to other options available to you?

Compared to other services that might offer lower-quality leads or require higher upfront costs/paywalls, Prime Tracers also give you free lead credits on sign up so you can actually see the results before you commit to a purchase.

Best pay compared to cost of living.

Compare that to the performance of a new property (with that equity unlocked but also with a different interest rate as @Katie Ripp said).

This has been well worth it compared to the 40+ hours I was previously spending doing this myself come tax prep time.

We recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

I find that depending on the market $300-500/mo are fairly normal and if compared to what you would pay with a single family home on some utilities, maintenance, and management, it's a good deal.

I really like LLCs compared to corporations because of the free stepped up basis for passing property to my children. 

I know you are dealing with a 3 month lease rather than a 12 month lease, but for example....Say I rent my home for $2,500 per month and have to lower my rate by $100 to find a quality tenant that is a loss of $1,200 over 12 months compared to a loss of $2,500 for each month it remains empty.
