Investing in real estate is capital intensive. There's a lot of courses and "gurus" out there who will suggest investing can be done with little or no money. This is merely to solicit mentees and buyers of their courses. Even Preston's example will do some who read this forum a disservice. Don't believe $19,000 is a sufficient amount of funds to execute a $480,000 total cost real estate opportunity. To elaborate:
The borrower in that scenario would have to pay for builder's risk and general liability insurance prior to closing & it's also not clear whether the closing costs were included in the $120,000.00 budget. But let's focus on the interest payments. Regardless of whether the interest payments were capitalized or paid outside of the loan (as is the case in Preston's example) what happens if there were delays and the interest reserve was depleted before the project is completed? The borrower was now paying out of pocket to cover the interest and this will be when the loan has been largely drawn down and the payments are at their highest. Or alternatively what happens when there were contingencies and the loan proceeds that were set aside for loan payments were required to complete the renovation. Borrower was still short cash to either complete the project or pay their loan payments.
Focusing on the renovation, the borrower required funds to not only begin the rehabilitation phase but the borrower would need additional funds to continue to advance the project. Whether the borrower used a 3rd party GC or oversaw the construction improvement, funds drawn through a construction loan are released in arrears. The borrower couldn't rely solely on the loan proceeds to efficiently move the project towards completion. Funds are needed at the beginning and funds are needed to make purchases for the longer lead time items such as kitchens, appliances, windows etc. Don't expect to find a sub-contractor base who requires no deposits (this is rare in the price point of this example).
Now fast forward to when the project is stabilized. If the borrower couldn't sell or the objective was always to refinance the property, most lenders want to see their borrowers have liquidity (otherwise the borrower's signature as a guarantor is worthless). This leaves the borrower with two options: bring in a co-guarantor who will take a piece of the deal or struggle to refinance and if the borrower succeeds on their own, the terms will be terrible.
Cash is necessary to successfully invest in real estate. It doesn't necessarily have to be your own, you can raise capital. However, there are a lot of real estate investors who get themselves in trouble by getting started without being properly capitalized. Being undercapitalized is just as likely to lead to a failed real estate investment as bad underwriting.
My objective is not to scare people from investing in real estate. I merely want to those who are interested to understand what is required to succeed.
