I’m a fan of using equity to scale up to multiply my cash flow.

It's a multiplier factor for everything. 

When you get a taste of renovating MF assets and see the multiplier effect of increasing NOI you’ll think that rehabs pay themselves 10x over.

That's your multiplier with the product being the the amount the tax rates are levied against. 

Multiply this by 27.5 and we have an average depreciable basis of $407,000.

Now for your question on what I need as an investor is either close to 25% below market or a value add that will return at least $250k with at least 2.5 multiplier on cost of value add versus value add (traditionally we have only required a 2x multiplier).  

It can be an absolute value or expressed as a % of sales.2️⃣ Capitalization Rate (Cap Rate) 💯 : This is the ratio of 'net operating income' to the purchase price (market value) of the property🔝.3️⃣ Cash-on-Cash Return (CoC) 💯: Cash available to Investros divided by Cash invested 🔝.4️⃣ Net Present Value (NPV) 🔢: NPV measures the present value of future cash flows generated by the investment, taking into account the cost of the investment 🔛.5️⃣ Internal Rate of Return (IRR) 💯: It is the rate of return that makes the present value of the future cash flows from the investment equal to its initial cost 🔝.6️⃣ Sales multiplier ❌: Sales multiplier is a key performance indicator used to measure Price of the asset in relation to assets sales, particularly in the rental and hospitality 🆗.7️⃣ Rent per Square Foot ➗: It is a Key Performance Indicator used to measure rental income, per squarefoot, often popular in CRE ♊ .8️⃣ Debt Service Coverage Ratio ➗: It is a measure of a property's ability to generate sufficient income to cover its debt obligations (Cash available for Debt divided by Loan installment) ⁉.9️⃣ The interest coverage ratio ➗: It measures a real estate asset's ability to cover its interest payments (Asset's net operating income (NOI) divided by Interest. ⁉.🔟 Debt-to-Equity Ratio➗: A measure of financial leverage, calculated by dividing its total liabilities by its shareholders' equity ⬇.

Well, I actually use a Gross Rent Multiplier (GRM; roughly 50 times the rent = price) to sift through the hoards of wantabe deals, and when I find one that fits I will run an actual income expense statement on it.The same would hold true for taking 50% of the gross rent as net operating income.

There's also what's called the "common level ratio" which they multiply the "market value" by to determine assessed value.

Any listings that have no subdivision or zip comps, I take the HUD value for "fair market rent" in the county, and based on previous analysis of the relationship to that value and actual market rent, I multiply the HUD value by 1.22.
