Just a follow up question, were you utilizing debt to invest, I have always been taught since a young age to try and not utilize debt (I come from a family of stock market investors, traditional business owners) where debt is not utilized as frequently which I obviously understand debt can be a very powerful tool and utilized in a great way its just something I want to avoid with my investments to an extent any suggestions for investing without debt or as little as possible. 

You will owe monthly payments until you fix the property up, rent it out, and refinance to a more traditional 30 year fixed rate product.

Quote from @Chris Seveney: @Francisco AvancenaThere are specific lenders who will do land dealsBut of course not as many as traditional real estate.The key will be skin in the game - typically for land because it is less liquid than a home the lender will want to have a lower ltv on the deal I fund land flippers currently in  CO FLA WA ID MT NV AZ OR TX SC GA VA  one thing about land though LTV is lower and RATES are NOT the same as typical HML rates are higher for raw land but its a specialty niche and a business that I grew up in..

With it being a difficult property for an investor to find traditional financing for, how would I go about assigning a realistic valuation for the property if we were to entertain a sale?

While the traditional approach involves buying a multi family property, living in one unit and renting out the other - with rising prices and interest rates; others have considered renting out bedrooms as unit spaces. 

Qualified renters can opt to pay a non-refundable monthly fee instead of a traditional deposit.

Unlike traditional banks and credit unions, we don't face the same constraints, allowing us to offer more flexibility.
