If the electric service comes through the roof, you can get a split boot that can be installed around the conduit, so you don't have to have the wires disconnected.If there are vents on the roof, you might think about replacing them as well. 

Once I have enough income from my rentals to survive frugally – the goal is no later than 30 – I want to start a construction company that services residential investors.

I added in vacancy (10%), property management (10%), maintenance (10%), $1k/yr for Contract services, $750/yr for legal costs, I escalated the taxes, insurance and utilities by 3% (numbers provided are from 2017).

For investments that are relatively static and singular in nature - shares of a private placement for example - the services of a self-directed IRA custodian can be sufficient. 

You need to think about how you are going to pay your monthly debt service with just a single solid tenant.Assuming you can get a commercial loan on that property your debt service is probably going to be $4-5k month.

Say 15% discount at purchase, followed by a further 5%+ appreciation during the year, not even including any value-adding that could have been made to its design)].Thank you for your service.

Listing agent emailed me his declaration of service for trial evidence.

How would you think a software service that caters solely to the project management of a flip/rehab would work for you?
