Thank you for your time and consideration.

The good news about the saturation is a lot of investors bought in the height of covid, with abnormally high performance numbers.

With your primary residence, things can be pretty straight forward in terms of splitting mortgage interest, real estate taxes etc. on your returns.If you go into a rental property, there are a lot of considerations to think about.

Ability to repay - can you as the borrower afford the payments based on the loan amount.Typically they will not take into consideration the mortgage on a new property that has not been taken out as that is new.

They’ve likely invested a considerable amount of time and money into it.

Government assistance/tax credits are of course a consideration that is factored in to the cost/benefit analysis of any form of new energy generation, as all forms of energy are heavily subsidized and always have been, long before solar entered the equation. 

Watch the old classic "Pacific Heights" and you will never want to be a LTR landlord, at least in California lol. 

Hello BP Community, I am located in Capitol Heights, Maryland.

If you have considerable equity in the property or multiple properties it's even more important.

This seems unlikely in the long run. you are forgetting that someone is paying down your principal for you so you need to take that into consideration.
