Hey Rob,
I have a few years experiance working in investment real estate in philadelphia and here are just some pro's and con's I have found with not only investing myself, but what I have heard from my clients.
Pros;
1.) Reliable on time payments
2.) High Allowable rent increases
3.) Fill vacancies faster
4.) Lower vacancy and turnover rates
5.) Potential for Higher rents
Cons;
1.) The bureaucracy can cost time and money, and delay new Section 8 tenants moving in. Worse yet, local housing departments often require extra steps in the eviction process, delaying eviction of non-paying Section 8 tenants. Which, in turn, means months of unpaid rent.
2.) Delayed Initial Payments-Sometimes your first payment can be delayed 2-4 months so you should account for months with no cashflow even after you get a tenant
3.) Tons of Inspections-This is the top reason many landlords do not accept Section 8 vouchers. An entire year of cashflow could be wiped out from repairs you have to complete from the high number of annual inspections.
4.)Tenant Quality- Without being said, yu get a lower quality tenant when using section 8
5.) Property damage- This one stems from the point above. With a lower quality tenant, you are at a higher risk of them damaging the property.
Hope this helps! Feel free to connect with me and ask any further questions you might have!
