There are lots of factors that can effect this! 

So I just saw this post about Section 8 HUD tenants, and this post stated something along the lines of section 8 tenants being more likely to damage properties because they're section 8 low income tenants, and also something about investors not wanting to put money needed into Section 8 properties because they think they're just going to be ruined by these Section 8 tenants, and as someone who knows the entire process with investors, owners, contractors, tenants, and prospective tenants, this is what I have to say about it:In my experience, Section 8 HUD tenants are actually better custodians of the property because of many factors, but 3 of the main reasons being, there is an annual HUD inspection that is performed on each property, so this gives the owner an extra 'protection vector' against damages, also, the initial placement of a Section 8 HUD tenant requires a passing HUD inspection, therefore there's a record of the property's initial state prior to move in, and additionally, they want to have an easy renewal voucher process annually, and their unit remaining in good condition is an incentive for those reasons, therefore they are LESS likely to damage a property - their future depends on it!

Imputed value comes from taking the assessed value from the tax assessor and multiplying by the applicable factor that the PA Dept of Revenue has determined for that county and year.

And make sure that all items necessary for you to get the best rate possible from your carrier (like 4 point inspections, roof attachment points, pool enclosures etc) are present or available.One nasty little factor that can't be helped is that every time you buy a property for more than than last owner paid - you will have a tax bump due to re-assessment. 

The interest rate on a loan is one factor (of many) you need to consider when building a rental portfolio.

When house-hacking with 5% down, returns on cash invested could be huge when you factor in the appreciation gains.

Marty,Avoid templates because they are specific to certain factors and by following someones BRRRR you open yourself up to mistakes. 

Issues like contractor delays, supply shortages, or unforeseen repairs can extend your timeline, which adds to your holding costs (mortgage, utilities, etc.).Tip: Factor in extra time for delays and have a backup plan to stay on track.Over-Renovating: Many new investors fall into the trap of over-improving a property, especially when they try to bring in their own taste.

Focuses on the ability to service debt, making it a key factor in financing decisions.

You will also have to factor in rental days vs. personal use days.This is very complicated.
