@Anita Ahuja Hi Anita! I would definitely be interested to know the location and the asset class of the property. I invest passively and am a syndicator of large apartment investments. 7% return is on the low Side, unless it is an A Class Asset in a High Growth market. Although, I imagine if the property is in a location like California or New York...this is considered a normal to good return.
When we look for a deal to purchase, raising rents cannot be the only way we can make the numbers work. The problem with this is it takes time to turn the units/leases in order to raise the rents. Also, upgrading apartments is typically done prior to the increase in rents (although we have increased rents without any upgrades at all). You should know if they plan to upgrade the apartments as they turn (as tenants move out), and how much they plan to spend on the upgrades. The location and demographics will dictate what types/quality of upgrades should be done in order to maximize your returns. You don't want to overdo the upgrades as you may not see the rent increase enough to cover your costs.
The investments we consider are B & C class assets (1970-1985 mostly). Value Add properties, which means they all require some level of upgrades to maximize rents.
Sophisticated investors seem to like the Waterfall Equity Split like you described...but the average investor finds it complicated. Therefore, we see mostly straight splits. For example: 10%+ Cash on Cash Return and 70%-80% Precipitation to the investors.
1-3% Acquisition Fee is what we have seen (1-2% is more typical)
1-2% Asset Management Fee is typical.
Hope this helps.
