But agree that the condition of the roof could be an issue for your lender and your potential insurance carrier.

You will need to supply 2-3 quotes from different General Contractor's or licensed builder for all work.Some things that can occur are builder/vendor issues with lack of inventory, broken material, employee "no shows", date of completed work extensions, bad work, additional costs not factored on blue prints or cost analysis, delayed permits.Keep in mind any delays or issues will slow down your clear to close/funding date.

In Oregon (not just in Portland) you can't preemptively issue a no-cause eviction due to a property sale unless you have an accepted offer.If you are going to make an offer to the tenants to move out early or prior to your property going up for sale that offer can't be for less than what they would be eligible to automatically receive via Rental Relocation Assistance.

If during the next 2.5 years, the owner redeems the property i get the money + interest back, but lets say they do not redeem the property. 3)  Within the last 6 -3 months of the expiration of the redemption period, I will file a petition at the circuit court for the tax deed 4)  At the same time, after filing the petition for deed, I will need to send "Notice of Expiration of period of Redemption" Take Notice to the county so they can mail it to the home owners and any interested parties informing them to redeem asap. 5) I will subtax early the following taxes as soon as they are generated by the county. 6) Inform the property owner in three ways, certified mail from the Circuit Court Clerk, being personally served by, the Sheriff’s office; and notice being published in a local newspaper. 7)If the taxes are not paid and the last date to redeem passes, the tax buyer can apply to the Circuit Court for an Order directing the County Clerk’s office to issue a tax deed to the tax buyer.

Instead of implementing a first right of refusal, there should be an option to buy their homes from them at a fair market value/paying to move their homes elsewhere or give them the first right.This is the real issue, we are not protecting tenants by solely giving them the first right of purchase.

Time zone differences can complicate addressing tenant issues or emergencies, and managing major repairs from a distance can be tough.

Regarding using funds from your LLC property business, you'll need to consult with a tax advisor to understand the implications and any potential issues with this approach.
