I'm an agent in addition to being an investor.  

When its included in a lease for real estate then the laws pertaining to residential rental security deposits in your state apply but when its separate you should have more leeway to get some additional deposit to protect you.

To determine price range, the first step is always figuring our how much you are pre-approved for; and that can vary significantly when you are looking at multi-unit properties because of the additional variable of rental income that can be included in qualifying.

Preparation is key, and relationships are everything.When closing a property deal, the funds typically required include a purchase deposit, which is refundable during the due diligence period, and an additional nonrefundable extension deposit.

In addition, the Grantor will probably be required to sign the same seller's affidavit that are needed for a non DIL closing. 

These are professionals with additional training and a stricter code of ethics.

Additionally, the price point is still cheap enough to find the 1% rule and positive cash flow and it's super landlord friendly (so you will never have to go through a 12 month eviction or anything close to that!).

Furthermore, whole note investments benefit from an additional 0.5% annualized yield and are entitled to a share of any extension fees charged to the borrower."  

Quote from @Don Miller: The following is not to express any level of happiness or unhappiness with the build:Received change orders totaling $14,970 for 18 additional loads of fill dirt over allotted amount in contract (fill dirt arrived in December 2022), 7 loads of septic sand over allotted amount, and rock excavation at the septic site.I deal with all of those issues on new builds.

There should have been change orders alerting you of the additional charges, which would have given you the opportunity to make budget decisions.Check your management contract and check all your conversations with the PMC.
