I paid him the normal closing cost, a few $ grand in fees, and a slightly higher interest rate than I might could have gotten conventionally. 

That is part of the problem with a lot of companies (I am not knocking insula as dont have all the info/facts just stating how the business works), they engage brokers to get them loans and the brokers collect a small fee. unfortunately many of the brokers may be similar to real estate wholesalers - have little to no experience. 

We actually have an in-house realtor who specializes in selling flips and can list your property for just a 1% listing fee.

Rates are generally better on a conventional loan when accounting for all fees and prepayment penalties.

It allows them to keep those afloat and can collect fees on that side by retaining ownership of the deal. 

Selling the PropertyIf your parents decide to sell, they could: Sell As-Is: At a current appraisal of $350k, they could walk away with a sizable profit (after transaction costs like realtor fees, taxes, etc.).

We embrace S8 applicants, but screen them just like any other applicant.Many have an entitlement mentality and try to leverage their S8 voucher by pretending to be helpless:1) A percentage won't apply because they expect a landlord to waive application fees for them.2) Many cry broke and expect a landlord NOT to charge them a security deposit.3) Many of those same S8 tenants trying to avoid paying a security deposit, won't make an effort to call the list of nonprofits we send them that will pay their security deposit if they apply.4) A lot of them try to avoid paying for utilities.

I am looking into a company right now that does rent guarantee insurance and also does in lieu of deposit will issue a bond that the tenant basically gets charged a monthly fee for.

Wholesalers (no offense to those in the comments) who are doing this without being a foreign entity are probably co-wholesaling which is on the borderline and practically acting as an agent without a license or getting referral fees by having actual wholesalers on the ground doing deals and they just provide the leads which is different than wholesaling.

I don't receive a referral fee I'm just happy to share as it took me going through several CPAs to find the right one.
