You will want to consult with a lawyer.In regards to your last two questions here's some background on what makes a contract valid and enforceable:Offer: A promise to do or not do something within a certain time period Acceptance: A clear and direct statement that all terms and responsibilities are accepted Consideration: A legal and adequate inducement given in exchange for the promise Capacity: The parties to the contract must have the legal capacity and competency to contract Awareness: A party must be aware of the contract Legality: The contract must be legal in the jurisdiction it will be operating in***Not legal advice*** Steps I would take: -Review contract in detail to understand each counterparties responsibilities (if you are not aware)- Email a copy of the lease to each of the tenants listed on the lease and reiterate lease expectations for termination notice, rent payment etc. - If the lease was signed via Docusign (other esign may have same ability) - you can go to the envelope, go to history and view the IP addresses for each action taken.

I see SO many properties in the upper midwest that have ample yards or even existing structures like carriage houses and detached garages yet prohibit ADUs.

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases:Class A Properties:Cashflow vs Appreciation: Typically, 3-5 years for positive cashflow, but you get highest relative rent & value appreciation.Vacancy Est: Historically 10%, 5% the more recent norm.Tenant Pool: Majority will have FICO scores of 680+ (roughly 5% probability of default), zero evictions in last 7 years.Class B Properties:Cashflow vs Appreciation: Typically, decent amount of relative rent & value appreciation.Vacancy Est: Historically 10%, 5% should be applied only if proper research done to support.Tenant Pool: Majority will have FICO scores of 620-680 (around 10% probability of default), some blemishes, but should have no evictions in last 5 yearsClass C Properties:Cashflow vs Appreciation: Typically, high cashflow and at the lower end of relative rent & value appreciation.

This being said, I don't believe we'll be able to meet the income requirements to qualify for a conventional.This leads me to believe hard money or private lender is more the only option to get my foot in the door, use my business to make repairs at very good rates, build some equity then refi once the balloon is due. 

I would say that it depends on the PM, I personally have a great connection with my local property manager in Memphis, TN and he manages over 700 doors and still answers my clients property management specific questions as the broker/owner.

On the investment side, student housing is my passion so adding a few doors to my portfolio in a college community would be ideal.For my personal residence, I would love to add a two-three car garage to my home.

Chicago title in the day their customer service department kept a spread sheet for me of all the NODS in the 4 county market of Portland OR that is 3 Oregon counties and clark co was across the river.. this spread sheet which they updated daily would show address  lien position and property tax and any other judgements like IRS .. this was a service to garner my RE companies business I had 50 agents at the time working for me plus all my personal volume .. then I had a team of door knockers who started knocking doors ONLY within 7 days of the sale date ( as thats when people get really motivated to do something) Once a deal was struck ( we negotiated how much we were going to pay them and how long they could stay ( rent free mind you) the deal was done over the kitchen table cashiers check to them in exchange for a deed to me..

In terms of small multifamily inventory, newer, with garages, symmetrical, good curb appeal, etc., are all ideal in my opinion. 

I would notify her in person and in writing (big note on her door) including quoting the clause in the lease where she is responsible, and tell her you will be inspecting to insure the heat remains on, high enough to protect your unit, or she will be breaking the terms of her lease and also liable for any damage done in the downstairs unit as well.
