The real question is what is the expected profit margin on the flip and what sort of documentable experience do you have.

Here are some options and considerations:Loan Against Equity/ETFs:Margin Loans:Description: Margin loans allow you to borrow money using your investments (such as stocks or ETFs) as collateral.Pros:You retain ownership of your investments.Generally quick access to funds.Interest rates can be relatively low compared to other types of loans.Cons:Your investments are used as collateral, so if their value declines significantly, you may face a margin call (requiring additional funds or securities).Interest rates can vary and may be higher than traditional loans depending on the lender and your creditworthiness.Securities-Based Line of Credit (SBLOC):Description: Similar to margin loans, SBLOCs use your securities (stocks, ETFs) as collateral, but they typically provide more flexibility and may not trigger margin calls as easily.Pros:Allows for ongoing access to funds as long as your collateral remains sufficient.Interest rates may be competitive.Cons:Similar risks of potential margin calls if the value of your securities drops significantly.Terms and interest rates can vary widely among lenders.Comparison with 401(k) Loans:401(k) Loans:Description: Borrowing from your 401(k) allows you to access funds without selling investments, using your retirement savings as collateral.Pros:Typically low interest rates.No credit check required.Interest paid on the loan goes back into your 401(k) account.Cons:Usually capped at a percentage of your vested balance (commonly up to 50% or $50,000).If you leave your job, the loan may need to be repaid immediately or could be considered a taxable distribution.Potential opportunity cost of missing out on market gains if funds are withdrawn from investments.Other Alternatives:Home Equity Line of Credit (HELOC):Description: If you own a home with equity, a HELOC allows you to borrow against that equity at typically lower interest rates than unsecured loans.Pros:Lower interest rates compared to other types of loans.Interest may be tax-deductible if used for home improvements (consult a tax advisor).Cons:Your home serves as collateral, so failure to repay could result in foreclosure.Personal Loans:Description: Unsecured personal loans can be used for various purposes, including investing, but typically have higher interest rates than loans secured by collateral.Pros:No collateral required.Funds can be used for any purpose.Cons:Higher interest rates and stricter eligibility criteria based on creditworthiness.I am a loan officer and we do some of the loans stated above.

If you are set to make your 30%, or whatever margin you want to make off it, then you are good to go.

Unfortunately, I see a lot of borrowers come looking for a refinance with an 800 credit score before reno, and then after reno, it looks like a 580, forcing them to sell a deal for an ok margin when they would have been much better off with a BRRRR as intended.

The business itself was worth little, as it was only marginally profitable.

Full metal stairs are always an option but that would completely blow the budget which already has a razor thin margin. 

I have a tractor and have successfully fed wildlife before doing this.However, there is not a lot of margin to make a profit as I see bare land selling actively in MLS listings for $2-4k more than what it will cost me to buy the tax sale and do a quiet title search (likely $3k apiece). 

Try to get the lot minimum $3-5k under what the comps are saying, for bigger profit margins.

Most builders operate with thin profit margins for the level of risk taken so it can be about the money. 

In Westminster, a growing suburb northwest of of Denver, the marginal difference in price for a 4br v a 5br is easy less per month than the extra $800-$1000/room in rent you get.
