Preparing to rent it as a short term rental, I read that there needs to be an authorized “responsible part” that lives within 30 miles from the property and able to respond to any issues within an hour.

If you have claimed this deduction or plan to in the future, ensure that your CPA or tax specialist is keeping up-to-date on the latest filings to ensure your documentation is correct.The new guidelines established that an allocation letter should include all of the following:The address of the government-owned buildingThe date the systems were placed in serviceThe signatures of the authorized representativesThe dollar amount of the deduction allocated to the designerThe allocation letter must be in writingThe costs of the energy efficiency systemsA penalty of perjury statement signed by the authorized representative of the government Must contain contact information for the authorized representative of both the owner of the government buildings and the designerDuring the audit, you can expect the IRS to confirm the energy modeling was conducted as well as ensuring that a third party professional completely unrelated to the project was the issuer of the certification.The 179D tax deduction should be claimed by the individual “primarily responsible for designing the energy efficient systems, and the person who creates the technical specifications for installation” for government buildings and designer allocations.When analyzing a 179D claim, the auditor will use “the most recent Standard 90.1 published by [ASHRAE] which has been affirmed… not later than the date that is 2 years before the date that construction of such property begins..

I was going to say the same thing as John in that I'd consider a limited POA written to give precisely enough authority to accomplish what you need. 

Of course, we certainly have SOME limitations, for example we must get written authorization for expenditure over a certain amount, usually the equivalent of one month rent or somewhat less except in emergency to protect life or property.

I just dont know where to start disputing this, if it is with the plumbing company first, with the HOA/MC who authorized the additional fixes, or just maybe eat the cost and try to put an insurance claim under my rental condominium policy if i can. 

We formed a two-person LLC and have equal authority.  

.) - I would approach the one you think would be the most amenable to having their mailing address used as a local contact.Alternatively, if you live close enough to the property where you fulfill these roles, I would appeal to the appropriate authorities with your situation, and explain to them that you understand the intent of that restriction, and that you fully intend to bear that responsibility even though your address is on the other side of a line some dude drew on a map many decades ago.A final "hail mary" might be that you set up a "Mailboxes Etc." post box or something similar. 

And, to be clear, THEY do not have authority to reach out to the vendor EXCEPT to return his call.

@Choice Crosby IIII don't know why you would want to assume the loan.You can buy the house subject to the existing loan it does not involve the bank whatsoever.It is a simple transaction that almost every title company knows to handle.Its a good business practice to have a few disclosures in place.And it's a must, to have 'authorization to release information' and a 'limited power attorney'given to you by the seller.

However, only licensed real estate agents and appraisers are authorized to access the MLS, making it tricky for other real estate professionals to run comps independently.Many real estate investors have found workarounds to this challenge, mainly through symbiotic relationships with licensed agents.
