The taxes and POS scare away many people but if you have the means to deal with them and factor in taxes, you can still make >11% COC fairly easily. 

Every month you are losing $1500 on this property between HOA and taxes, did you factor this in? 

Whenever you plan to purchase a tax lien certificate, you must factor in average attorney costs and other possible costs such as maintenance (to avoid weed liens, etc.) and future taxes.  

Keep in mind that this will be factored in when considering your offer.If the tenants are on month to month leases in RI, the seller can terminate their lease with 30 days notice. 

An ideal candidate would be someone who could get a survey within a week or two.

-why did you go that route with the market you're in (what market factors impacted your decision)?

This factor will impact your expense ratio, and ultimately the value of the park. 

Account ClosedThere are many factors that affect your credit score, but lack of income generally isn't one of them. 

If you're not owner occupying it, be prepared for a 75% LTV loan, so if you're putting down 10% now, be prepared to have the other 15% in order to refi (not factoring in principal paydown or appreciation/depreciation of the property).Separate from the seller finance, make sure the rental numbers make sense.

I've purchased them as high as 82, but I like to stick with 50.Of course lots of other factors to consider (taxes, insurance, vacancy, appreciation potential, maint).
