Two new posters here and the first thing you trying to do is to promote your $39 a month software?

I am more than happy to speak with anyone looking at the software and have recommended it to several people.

Waiting on seller confirmation to sign that (crucial part I expect hah)Some good news, got the inspector back to finish the job, and contractors for plumbing, HVAC and framing to come in today and I am waiting to hear back what sort of work needs to be done. 

Regardless,1) Make sure the modular home is affixed to the land. 2) Do some research to confirm these modulars are financeable.

Normally they're set up to take a lot of your money and sell you some kind of monthly software subscription.Search google for a white paper on tax lien/deed investing in your state. 

I know it's not specific software for mileage or book keeping but I have 4 properties, have been doing this for 3 years, and just made a simple google sheet to track everything. 

Do they have software in place for accounting, tenant ledgers, or inspections?

Quote from @Deborah Lee: Software is a common question on BiggerPockets.

On the plus side of where we are; rents have really shot up, we have far better RE investing tools, as well as better software and knowledge.

They can help confirm which markets to invest in and which ones to avoid.
