what are you hoping to accomplish by buying out of state in an area where the mechanicals would get stolen?? 

Quote from @Lionel Quiambao:  ... and maybe throw in the option for the tenant for more speed at an increased rent to cover the additional payment. 

My original SFR was 1100sf and I added 2 units: an 800sf SB9 unit and a 750sf ADU (converted garage plus addition).

If you let us know more about what you're trying to accomplish I may be able to point you in the right direction.

Next, arrange a site walkthrough to pinpoint any additional needs or potential challenges.

Additionally, in the R-7 and R-8 Zoning Districts, you need a Conditional Use Ordinance from the City Council to authorize the conversion.

Are there additional factors you think are worth considering?

In addition, committing ~ $200K requires some level of sophistication on the part of the investor and you are more likely to find someone to agree to your terms in smaller transaction sizes, but even that will be difficult. 

It is currently a glorified finished attic with little room- Use addition and raise it up and extend it to the side of the home for more finished space and room for deck, washer/dryer room etc- Make the living space as functional as possible with the added sqft- Add outside living structures like deckThis is a fairly wealthily area and I want to maximize my ROIWhat are some things you recommend for a large scale project like this and what are some hurdles ?

We have not disabled ours or converted to gas, but Tenant must sign a Fireplace Addendum stating if they use it, we require a higher renter's liability policy with us as additional insured, rules on wood, storage, use, safety, they pay for yearly professional cleaning each year they are there, etc.
