This sudden jump in rates has not fully caught up with market cap rates yet since especially in the commercial and multifamily property markets, transactions typically take 6 months to transact, creating a lag effect between interest rates and market cap rates since interest rates adjust daily.

I use standard market PM rates in my underwriting, but I also would not work for those rates but it is fair compensation for the work.I typically use vacancy of 5% not because I have ever had a unit that had that high vacancy but I do not have a no payment category and I want the underwriting to be conservativeon the opposite, your rate is a bit high and your appreciation rate and rent growth are modest.overall, seems like a decent attempt at an analysis.  

-------------------------------------------------------------------------------------------------------Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

We typically do 4-5 years interest only while paying down the principle balances over time.

-Max LTARV is typically 75% -Is a 12-24 Month Interest-only loan with a balloon payment - Minimum credit score is typically 600 -Interest on the Rehab is usually paid per the total drawn amount. 

Consult you insurance broker for specifics but I found this policy to be very protective and reasonably priced.With regards to an umbrella policy they are typically good to have.  

I know these lines of credit are typically variable rate and interest only but when I am buying deals with 20-25% equity that are new construction and cashflow around $500/mo with this loan option, I feel like I have hedged against those risks fairly well.

Typically it’s a secondary use meaning the land must have a primary use (like a home on it).

@Richard Benjamin WilhiteSince you inherited the land, I believe your cost basis is typically the land's fair market value at the time of inheritance. 

Also, there’s much to delve into on of those scenarios, like what type of cashflow or investment do you want, etc. residential, multi-res, small multi-res, commercial, industrial, etc.There seems to be fewer deals around these days and this typically benefits the more experienced and skilled investors but there are always multiple investors that get “tripped-up” in these markets due to them relying on recent “fortunate” market circumstances only to realize the markets cycle and they weren’t prepared or didn’t underwrite properly to account for unforeseen potential.There are more considerations, but this is a start.
