I recently received a letter from People's Gas regarding a Landlord Reversion Agreement.

Is this is a size thing (company just needs to get bigger/have more equity), or perhaps a business structure issue, or should I be looking at different financing sources other than local banks?

Find a reputable roofing company-look at online reviews and find one that has been in business for a while...ideally local company.Inspect the roof-are shingles curling? 

I am sure this is true for many people who invest.

However, I received rejections even after sending them my current work along with the pitch deck Sounds like you are avoiding the most important terms of your proposal, and you avoid telling us what parts of your proposal they object to, so I have no wonder why they don’t want to do business with you.

I’ve tried to look up municipal codes online in regards to rent by the room and limits on unrelated people living in the same home and have had no luck.

I had to take a break from my RE business because of my corporate career.  

For example; 80% of my business is servicing investors seeking vacation rentals where less than 1% of listings can qualify for a vacation rental permit.

Flipping is , IMHO, running a business.

If I were to do this, which I don't plan to for at least a few months (I would like to properly do my research) I was also curious whether or not people thought interest rates on HELOC LOANS were going to start going down or continue going up?
